Multilayer Ceramic Transient Voltage Suppressors
AVX TRANSGUARD - MULTILAYER VARISTORS
The AVX TransGuard® Varistors - Transient Voltage Suppressors (TVS) with unique high-energy multilayer construction represent state-of-the-art overvoltage
circuit protection. Monolithic multilayer construction provides protection from voltage transients caused by ESD (e.g. IEC 61000-4-2), lightning, inductive
switching, automotive related transients such as load dump (ISO 7637-2-5), jump start with and other automotive transients (e.g. ISO 7637 Pulse 1-3,
AEC-Q200-002, ISO 10605, ISO 16750-2, CI-220, CI-260) and more.
AVX varistors provide bi-directional transient voltage protection in the on-state and EMI/RFI attenuation in the off-state which allows designers to combine the
circuit protection and EMI/RFI attenuation function into a single highly reliable device. Parts are designed for use in temperatures from -55°C to +125°C (+150°C
components available) with no derating, exhibit very fast response, multiple strikes capability and high reliability. In addition, AVX automotive series varistors

Introduction
Multilayer Ceramic Transient Voltage Suppressors
TRANSGUARD® DESCRIPTION
TransGuard® products are zinc oxide (ZnO) based ceramic semiconductor
devices with non-linear voltage-current characteristics (bi-directional) similar
to back-to-back zener diodes. They have the added advantage of greater
current and energy handling capabilities as well as EMI/RFI attenuation.
Devices are fabricated by a ceramic sintering process that yields a structure
of conductive ZnO grains surrounded by electrically insulating barriers,
creating varistor-like behavior.
AVX VG series parts (large case size, high energy) are glass encapsulated.
These parts provide the same high reliability as traditional VC series parts.
The glass encapsulation provides enhanced resistance against harsh
The number of grain-boundary interfaces between conducting electrodes
determines “Breakdown Voltage” of the device. High voltage applications
such as AC line protection require many grains between electrodes while low
voltage requires few grains to establish the appropriate breakdown voltage.
Single layer ceramic disc processing proved to be a viable production
method for thick cross section devices with many grains, but attempts to
address low voltage suppression needs by processing single layer ceramic
disc formulations with huge grains has had limited success.
AVX, the world leader in the manufacture of multilayer ceramic capacitors,
now offers the low voltage transient protection marketplace a true multilayer,
monolithic surface mount varistor. Technology leadership in processing thin
dielectric materials and patented processes for precise ceramic grain growth
have yielded superior energy dissipation in the smallest size. Now a varistor
has voltage characteristics determined by design and not just cell sorting
whatever falls out of the process.
Multilayer ceramic varistors are manufactured by mixing ceramic powder in
an organic binder (slurry) and casting it into thin layers of precision thickness.
Metal electrodes are deposited onto the green ceramic layers which are then
stacked to form a laminated structure. The metal electrodes are arranged
so that their terminations alternate from one end of the varistor to the other.
providing uniform energy dissipation in a small volume.

GENERAL DESCRIPTION
TransGuard® multilayer varistors are zinc oxide (ZnO) based ceramic semiconductor devices with non-linear
voltage-current characteristics (bi-directional) similar to back- to-back zener diodes. They have the added
advantage of greater current and energy handling capabilities as well as EMI/RFI attenuation.
The increasing use of electronics technologies in all areas require reliable protection against transient voltages
that could damage the electronics circuitry as well as EMI/RFI attenuation to prevent signal distortion and to
meet regulatory requirements. AVX TransGuard components help achieve both functions with single component.

TransGuard®
Multilayer Ceramic Transient Voltage Suppressors
TYPICAL PERFORMANCE CURVES (0402 CHIP SIZE)
VOLTAGE/CURRENT CHARACTERISTICS
Multilayer construction and improved grain structure result in excellent
transient clamping characteristics up to 20 amps peak current, while
maintaining very low leakage currents under DC operating conditions. The VI
curves below show the voltage/current characteristics for the 5.6V, 9V, 14V,
18V and low capacitance StaticGuard parts with currents ranging from parts
of a micro amp to tens of amps.
PULSE DEGRADATION
Traditionally varistors have suffered degradation of electrical performance
with repeated high current pulses resulting in decreased breakdown
voltage and increased leakage current. It has been suggested that irregular
intergranular boundaries and bulk material result in restricted current
paths and other non-Schottky barrier paralleled conduction paths in the
ceramic. Repeated pulsing of TransGuard® transient voltage suppressors
breakdown voltage and minimal increases in leakage current.

StaticGuard
Multilayer Ceramic Transient Voltage Suppressors
TYPICAL PERFORMANCE CURVES (0402 CHIP SIZE)
VOLTAGE/CURRENT CHARACTERISTICS
Multilayer construction and improved grain structure result in excellent
transient clamping characteristics up to 20 amps peak current, while
maintaining very low leakage currents under DC operating conditions. The VI
curves below show the voltage/current characteristics for the 5.6V, 9V, 14V,
18V and low capacitance StaticGuard parts with currents ranging from parts
of a micro amp to tens of amps.
PULSE DEGRADATION
Traditionally varistors have suffered degradation of electrical
performance with repeated high current pulses resulting in decreased
breakdown voltage and increased leakage current. It has been
suggested that irregular intergranular boundaries and bulk material
result in restricted current paths and other non-Schottky barrier
paralleled conduction paths in the ceramic. Repeated pulsing of
TransGuard® transient voltage suppressors with 150Amp peak 8 x
and minimal increases in leakage current.

MultiGuard Series
(2&4 Elements) Multilayer Ceramic Transient Voltage Suppression
Arrays – ESD Protection for CMOS and Bi Polar Systems
GENERAL DESCRIPTION
AVX’s Transient Voltage Suppression (TVS) Arrays address six trends in today’s electronic circuits: (1) mandatory ESD
protection, (2) mandatory EMI control, (3) signal integrity improvement, (4) PCB downsizing, (5) reduced component
placement costs, and (6) protection from induced slow speed transient voltages and currents.
AVX’s MultiGuard products offer numerous advantages, which include a faster turn-on-time (<1nS), repetitive strike
capability, and space savings. In some cases, MultiGuard consumes less than 75% of the PCB real estate required for
the equivalent number of discrete chips. This size advantage, coupled with the savings associated with placing only
one chip, makes MultiGuard the TVS component of choice for ESD protection of I/O lines in portable equipment and
programming ports in cellular phones. Other applications include differential data line protection, ASIC protection and
LCD driver protection for portable computing devices.

UltraGuard Series
ESD Protection for Low Leakage Requirements
GENERAL DESCRIPTION
Faster semiconductor clock speeds and an increasing reliance on batteries as power sources have
resulted in the need for varistors that exhibit very low leakage current. The UltraGuard (UG) Series
of AVX Transient Voltage Suppressors address this problem.
The UG Series is the ideal transient protection solution for high clock speed integrated circuit
application, battery-operated device, backlit display, medical/instrument application, low voltage
power conversion circuits and power supervisory chip sets. In addition, UltraGuard’s low leakage
characteristics are also suitable for optic circuits like LDD, SerDes, and laser diodes.

Communication BUS Varistor
GENERAL DESCRIPTION
The CAN BUS and FlexRay varistor is a zinc oxide (ZnO) based ceramic semiconductor device with non-linear voltage-
current characteristics (bi-directional) similar to back-to-back Zener diodes and an EMC capacitor in parallel (see
equivalent circuit model). They have the added advantage of greater current and energy handling capabilities as well
as EMI/RFI attenuation. Devices are fabricated by a ceramic sintering process that yields a structure of conductive ZnO
grains surrounded by electrically insulating barriers, creating varistor like behavior.
AVX Communication Bus Varistors offer the advantages of large in-rush current capability, low capacitance to minimize
through their bulk capacitance. These features coupled with an extremely low FIT rate and excellent process capability
make an ideal device for today’s automotive or general circuit protection.

& 0603 chips), 2 and 12pF (0603 chip). These low capacitance values have low
insertion loss, as well as give other TransGuard® advantages such as small size, sub-
nanosecond response time, low leakage currents and unsurpassed reliability (FIT
Rate of 0.2) compared to diodes.
circuit designers today, given the combination of increased signal “gain” demands,
coupled with the required downsizing of the transistor package. The ability to achieve
both objectives is tied to a reduced thickness of the SiO2 gate insulator layer within
the semiconductor. The corresponding result of such a change increases the Power
electronic products with RF transmitting and/or receiving features. AVX Low

ESD Protection for Antennas and Low Capacitor Loading Applications
ANTENNA VARISTORS
AVX offers a series of 0402 and 0603 chip varistors, designated the
packages), as well as low insertion loss. Antenna varistors can replace
output capacitors and provide ESD suppression in RF and capacitance
sensitive applications.
very susceptible to ESD damage due to the very thin layer of SiO2 uses as
the gate insulator. The ultra-thin SiO2 layer is required to improve the gain of
the transistor. In other words, the upside of the performance enhancement
becomes the downside of the transistors survival when subjected to an
ESD event.
ESD damage to the RF Field Effect Transistors (FETs) is a growing concern
trends relate to decreasing gate oxide thickness, which in turn, is directly
proportional to increased ESD sensitivity. As miniaturization trends
accelerate, the traditional methods to protect against ESD damage (i.e., PC
effective.
AVX’s AntennaGuard varistor can be used to protect the FET and offer
superior performance to the previously mentioned protection methods
given above. The standard EIA 0603 chip size, and particularly the 0402
chip, offer designers an ESD protection solution consistent with today’s
downsizing trend in portable electronic products. Savings in component
volume up to 86%, and PC board footprint savings up to 83% are realistic
expectations. These percentages are based upon the following table and

TransFeed
AVX Multilayer Ceramic Transient Voltage Suppressors
TVS Protection and EMI Attenuation in a Single Chip
GENERAL DESCRIPTION
AVX has combined the best electrical characteristics of its TransGuard®
Transient Voltage Suppressors (TVS) and its Feedthru Capacitors into
a single chip for state-of-the-art overvoltage circuit protection and EMI
reduction over a broad range of frequencies. This unique combination of
designer a single 0805 chip that responds to transient events faster than any
when in the off-state.
The reduction in parallel inductance, typical of the feedthru chip construction
when compared to the construction of standard TVS or ceramic capacitor
chips, gives the TransFeed product two very important electrical advantages:
(1) faster “turn-on” time. Calculated response times of <200 pSec are not
unusual with this device, and measured response times range from 200 –
250 pSec. The TransFeed “turn-on” characteristic is less than half that of an
equivalent TransGuard®® clamp transient voltages
faster than any other bipolar TVS solution such as diodes; (2) the second
electrical advantage of lower parallel inductance, coupled with optimal series
inductance, is the enhanced attenuation characteristics of the TransFeed
Interface I/O Lines, Power Line Conditioning and Power Regulation.

PERFORMANCE CHARACTERISTICS
FEEDTHRU VARISTORS
AVX Multilayer Feedthru Varistors (MLVF) are an ideal choice for system
designers with transient strike and broadband EMI/RFI concerns.
Feedthru Varistors utilize a ZnO varistor material and the electrode pattern
of a feedthru capacitor. This combination allows the package advantage of
the feedthru and material advantages of the ZnO dielectric to be optimized.
ZnO MLV Feedthrus exhibit electrical and physical advantages over standard
ZnO MLVs. Among them are:
1. Faster Turn on Time
2. Broadband EMI attenuation
3.
The electrical model for a ZnO MLV and a ZnO Feedthru MLV are shown
below. The key difference in the model for the Feedthru is a transformation
in parallel to series inductance. The added series inductance helps lower the
lower clamping voltage. The lowered parallel inductance decreases the turn
on time for the varistor to <250ps.

AVX Multilayer Ceramic Transient Voltage Suppressors
TVS Protection and EMI Attenuation in a Single Chip
GENERAL DESCRIPTION
AVX has combined the best electrical characteristics of its TransGuard®
Transient Voltage Suppressors (TVS) and its Feedthru Capacitors into
a single chip for state-of-the-art overvoltage circuit protection and EMI
reduction over a broad range of frequencies. This unique combination
the circuit designer a single 0805 chip that responds to transient
events faster than any TVS device on the market today, and provides
Automotive TransFeeds are designed for automotive applications and
The reduction in parallel inductance, typical of the feedthru chip
construction when compared to the construction of standard TVS
or ceramic capacitor chips, gives the TransFeed product two very
important electrical advantages: (1) faster “turn-on” time. Calculated
response times of <200 pSec are not unusual with this device, and
measured response times range from 200 – 250 pSec. The TransFeed
“turn-on” characteristic is less than half that of an equivalent
TransGuard®® clamp transient voltages faster
than any other bipolar TVS solution such as diodes; (2) the second
electrical advantage of lower parallel inductance, coupled with optimal
series inductance, is the enhanced attenuation characteristics of the
at a higher self-resonance frequency, but the roll-off characteristic
on Microcontroller I/O Lines, Interface I/O Lines, Power Line
Conditioning and Power Regulation.

General Applications (TransGuard®)
AVX Multilayer Transient Voltage Protection
Circuit Protection in Automotive Applications
AUTOMOTIVE TRANSIENTS
Todays automobiles are using new technologies based on electronics
systems connected by wide variety of networks to provide increased safety,
convenience and comfort, to reduce emissions, increase
During the lifetime these systems are subjected to many overvoltage
transient surges. To ensure safe and reliable function it is necessary to
protect these sensitive systems against overvoltage surges.
AUTOMOTIVE POWER RAIL TRANSIENTS
The transients on automotive power rails are usually medium to high energy
transients and are caused by engine start such as Jump start (connecting
other cars battery to jump start the engine), Load Dump (sudden load
disconnect from alternator) or inductive switching (caused by DC motors
on/off switching - e.g. window lifter, wipers, adaptive headlights). These
transients are typically bi-directional.

AUTOMOTIVE DATA LINE TRANSIENTS
Data lines connecting the automotive systems need to be protected against
varisous ESD pulses to ensure sensitive electronics protection. These
transients are mainly caused by human interaction with the electronics
systems (controls, buttons, ports) or by interaction between systems due to
different charge build up. These transients are typically
bi- directional and very fast.

Automotive Application (TransGuard®)
AVX Multilayer Transient Voltage Protection
Circuit Protection in Automotive Applications
MLVs have traditionally been used in inductively generated automotive
transient suppression applications such as motors, relays and latches.
MLVs offer a large in rush current capability in a small package, high-
capacitance. These, coupled with an extremely low FIT rate and excellent
process capability makes MLVs a common device in today’s intermediate to
high power automotive circuit protection.
AUTOMOTIVE COMMUNICATION BUS
AVX varistors are indeal choice for automotive circuit protection thanks to
from low capacitance components for high speed data lines/RF circuits up
to high energy varistors for load dump and jump start requirements on power
lines or low speed data lines such as LIN Bus. AVX also offers automotive
EMC system performance.
Automotive electronic systems are connected by various network systems
depending on the data speed requirements. Most common networks include:
LIN (LOCAL INTERCONNECT NETWORK)
LIN Bus operates at slower data speeds up to 20kbps and provides reliable
low cost automotive networking. Typical applications are e.g. window lifter,
door lock, seat controls, mirror controls, wipers, rain sensors etc.
CAN (CONTROLLER AREA NETWORK)
CAN Bus is is a vehicle bus standard designed to allow microcontrollers
and devices to communicate with each other within a vehicle without a host
computer. CAN Bus supports data speeds up to 1Mbps. Typical applications
are ECU connection to transmission, door locks, adaptive headlights, climate
control, etc.
MOST (MEDIA ORIENTED SYSTEMS
TRANSPORT)
MOST is standard for high-bandwidth automotive multimedia networking.
This network provides excellent Quality of Service and seamless connectivity
for audio/video streaming through variety of multimedia interfaces such as
DVD player, head set, voice control.
FLEXRAY
FlexRay is an automotive network communications protocol to govern on-
board automotive computing. It is designed to be faster and more reliable
than CAN and TTP intended for drive-by-wire applications.

Designers have the option of using AVX TransGuards®
to meet IEC 61000-4-2, 3 and 4.
In the case of IEC 61000-4-2 TransGuards® can be used to suppress the
incoming Transient just like a Zener diode would. TransGuards®, however,
exhibit bipolar characteristics, a faster turn-on-time (<1nS), a better repetitive
strike capability and superior thermal stability to the Zener suppression
device. Furthermore, TransGuards® are typically smaller and lighter when
placed on SMT circuit boards. See Figure 1 for data illustrating IEC 61000-4-2
repetitive strike capability.
The TransGuards® effective capacitance allows the device to be used to
meet IEC 61000-4-3 and 61000-4-4. The device’s parallel capacitance can be
used as effectively as a capacitor to block low level incident and conducted
RF energy. If in the case of some levels of IEC 61000-4-3 and IEC 61000-4-4
when the intensity of pulse is greater than the device’s breakdown capability
it will then turn on and suppress via MOV means rather than capacitance (as
in the small signal case). Effectiveness hinges upon the proper placement
of the device within the PCB (which is usually easily accomplished since
TransGuards® are so small).

Application Notes:
INTRODUCTION
Due to the growing importance of ESD immunity testing, as required
by the EMC Directive, proper selection of voltage suppressor devices
is critical. The proper selection is a function of the performance of
the device under transient conditions. An ideal transient voltage
suppressor would reach its “clamping voltage” in zero time. Under the
conditions imposed by the 1991 version of IEC 61000-4-2, the actual
turn-on-time must be less than one nanosecond to properly respond to
It has been found during testing of transient suppressors that the
response time is very closely dictated by the packaging of the device.
Inductance that is present in the connection between the silicon
die and the leads of the device creates an impedance in series with
the suppressor device; this impedance increases the overall device
response time, reducing the effectiveness of the suppressor device.
The purpose of this paper is to present the Turn on Time characteristics
of Multilayer Varistors (MLVs) and to compare the MLV Turn on Time to
that of various silicon transient voltage suppressors (SiTVs).
The Turn on Time of a transient voltage suppressor (TVS) is of growing
a rise time < 1 ns. Therefore, TVS’s must have a turn on time < 1
ns to effectively suppress ESD. In many, if not all, ESD suppression
applications, TVS turn on time can be of more importance than
absolute clamping voltage (Vc) of the TVS (assuming that the TVS
clamping voltage is less than the damage voltage of the circuit or IC).
To measure the turn on time of today’s TVS’s, a broad cross section
of MLVs and SiTVs were chosen. Only surface mount devices were
chosen in order to best represent today’s TVS current usage/trends
and to keep the test matrix to a reasonable level of simplicity. The
following devices were tested:

The graph shows the voltage attenuated by a factor of 1000, with a 800ps
risetime for the ESD waveform (this agrees with typical data given by Keytek
for equipment performance). It should be noted that only the positive polarity
was tested. Prior testing showed turn on time was not dependent upon
waveform polarity (assuming that DUTs are bidirectional).
TEST RESULTS
MLV TURN ON TIME TRANSGUARDS®
The turn on time test results for AVX TransGuards® showed that all case
sizes were capable of a sub-nanosecond turn on response. This corresponds

TVS TURN ON TIME
Test results for SiTVs varied widely depending upon the physical size and
several SiTVs manufacturers papers indicating that the absolute response
from the silicon die could be < 1 ns. However, when the die is placed in a
package, the turn on time delay increases dramatically. The reason for this
is the series inductance of the SiTVs packaging decreases the effective
response time of the device. Reports of 1-5 ns are frequently referred to
in SiTVs manufacturers publications. Further, the turn on times for SiTVs
vary dramatically from manufacturer to manufacturer and also vary within
a particular manufacturers lot. The data provided in the following table

sub-nanosecond turn on time. Although the silicon die of a SiTVs has a sub-
nanosecond response, the packaged SiTVs typically has a response time
much slower than a TransGuard®. If the two devices were directly compared
on a single graph (see Figure 4), it could be shown that the TransGuard®

Application Notes:
The purpose of this discussion is to recap the impact ESD has on portable,
battery powered equipment. It will be shown that ESD can cause failures
failures can be caused by one or more of its complex components:
Predischarge - Corona Generated RF
Predischarge - E Field
Discharge - Collapsing E Field
Discharge - Collapsing H Field
Discharge - Current Injection...Voltage...Additional Fields
With this in mind it will be shown that the only way to insure equipment
survivability to ESD is to use a Transient Voltage Suppressor (in addition to
proper circuit layout, decoupling, and shielding).
In order to get a better understanding of what happens in an ESD event the
equivalent of the human body model is shown in Figure 1. Typically, the
charge developed on a person can be represented by a 150pF capacitor
in series with a resistance of 330 ohms. The energy of an ESD waveform
generated from this model is Q = 1/2 CV2 where Q = total energy in Joules, C
= capacitance of the human body model in farads and V = charging voltage
in volts.
Voltages can be as high as 25 kV, however typical voltages seen are in the 8
to 15 kV regions.
Figure 1. Human Body Model
PREDISCHARGE E FIELD FAILURES
Figure 2. Pre-Discharge Scenario
In the predischarge scenario (Figure 2) a human charged to –20 kV may
approach a battery powered “system” on a table. As the person reaches
toward the system electrostatics dictate that the system will have an equal
and opposite charge on the system’s surface nearest to the person. SInce
the system we are approaching is isolated from ground, the charge is only
redistributed among the device. (If the system were grounded a current
would be generated by the loss of electrons to ground. The system would
then become positive relative to ground). The rate of approach of the human
body model affects the charging current to a small extent. However, most
developed across the equipment that cause the destruction of components
within the system. In general, unprotected IC’s (particularly CMOS) are
further complicated by the device type and complexity and the fact that
the breakdown voltage of a generic IC will vary greatly from manufacturer
to manufacturer (Figure 3). This brief discussion should be adequately
IC protection can be achieved by placing a transient suppressor on the most
susceptible pins of the sensitive IC’s (e.g., Vcc and I/O pins, etc.).
Figure 3. IC Type E Field Susceptibility
CONTACT DISCHARGE FAILURES
As the charged person gets closer to the system, the situation is more
complex. First a much more detailed human body model is needed to
represent the complex transmission line which will transport energy to the
system (see Figure 4). In this discussion we will only consider the case of a
single contact discharge. In the real world, however, multiple discharges will
likely occur (possibly caused by a person’s hand reacting to an ESD spark
and then touching the system again, etc.).
In contact discharge, when a charged person approaches the system,
intensity becomes greater, eventually reaching a point large enough to draw
an arc between the person and the system. In contrast to the noncontrast

The model shown on Figure 4 can be broken up into 4 sections for the sake of
Section 2 takes into account how the human body model gets the energy
to the system. This section considers the inductance, resistance and
ground and the system.
The third section is the inductance and resistance of the arc which is created
as section 2 approaches the system (Section 4).
Section four is the system itself.
The combination of the capacitances and inductances in these sections form
a complex network of LC tank circuits which will inject a variety of waveforms
(transients) into the system. These waveforms will range in frequency from
very high (5 GHz) to high (100 MHz) to low (20-50 MHz) plus a variety of
under damped and over damped waveforms.
Finally, in addition to current/voltage injection occurring as a result of the
frequency RF waveforms. Many times these waveforms propagate into
shielded equipment and cause system/device failures.

SUMMARY
electrostatics (as in the person being close to the system but not touching
it) can be eliminated by shielding. This is usually not the case because it
shielding will likely have seams, ventilation holes, or I/O ports which represent
generated RF can be a problem. Finally, if the system has I/O connectors,
keyboards, antennas, etc., care must be taken to adequately protect them
from direct/and indirect transients. The most effective resolution is to place
a TransGuard® as close to the device in need of protection as possible.These
recommendations and comments are based upon case studies, customer

been associated with running motors.
This study is aimed at evaluating how TransGuards® can reduce EMI from
running motors and clamp transients generated from relays and motors
during power off.
DESCRIPTION
Three different motors and two different relays were chosen to represent the
wide range of possible devices used by designers. Device choices were as
follows:
MOTORS
Cramer 8001 series Geared Motor
12V, 30rpm (4800 RPM armature speed) 170ma
Start/Run Torque 30oz
Comair Rotron DC Biscut Fan - 24V, 480ma
Comair Rotron DC Biscut Fan - 12V, 900ma
RELAYS
A Tektronix TDS 784A four channel 1GHz 4G S/s digitizing storage scope
A x10 probe was connected to the scope and one leg of the relay/motor coil;
the probe’s ground was connected to the other relay coil/motor wire. The
scope was triggered on the pulse and waveforms printed.
When suppression was introduced into the circuit, it was placed directly on
the relay coils/motor lead wires. The axial TransGuard® and capacitors had
it was determined that this was a fairly common lead length for such
applications.
SUMMARY
GEARED MOTOR
The Cramer geared motor was tested while running (under load) to
determine its “on state” noise as well as under loaded turn off conditions.
Both TransGuards® and ceramic capacitors were tested to determine the
level of protection they offer.
A 14V axial TransGuard® provided the best protection during running and
turn off. The VA100014D300 TransGuard® cut the 60V unprotected turn off
voltage spike to 30V. It also cut the on state noise to 4.0V pk-pk due to its
internal capacitance. The following is a summary of measured voltages
(scope traces are shown in Figures 1, 1A, 2, 2A).

Application Notes:
The current trend in automobiles is towards increased performance,
are incorporating an ever increasing array of electronics into cars. As the
electronic content within cars increases, auto manufacturers are utilizing
multiplex bus designs to network all the sensors to a central point (usually
the engine control unit [ECU]). Multiplex lines save wiring harness weight
and decrease the harness’ complexity, while allowing higher communication
speeds. However, the multiplex structure tends to increase the occurrence
and severity of Electromagnetic Interference (EMC) and Electrostatic
Discharge (ESD).
Multilayer varistors (MLVs) are a single component solution for auto
manufacturers to utilize on multiplex nodes to eliminate both ESD and EMC
problems. MLVs also offer improved reliability rates (FIT rates <1 failure/
billion hours) and smaller designs over traditional diode protection schemes.
TYPICAL MUX NODE APPLICATION
There are a variety of SAE recommended practices for vehicle multiplexing
(J-1850, J-1939, J-1708, J-1587, CAN). Given the number of multiplexing
considerably.
Each node has an interface circuit which typically consists of a terminating
resistor (or sometimes a series limiting resistor), back to back Zener diodes
(for over voltage protection) and an EMC capacitor. Such a method is
compared to that of a multilayer varistor in Figure 1.

MLV node protection methods.
To more clearly understand the functional structure of a MLV, see the
equivalent electrical model shown in Figure 2.

improves system reliability. The MLV offers many additional electrical
improvements over the Zener/passive schemes. Among those advantages
are higher multiple strike capability, faster turn on time and larger transient

CONSTRUCTION AND PHYSICAL
COMPARISON
The construction of Zinc Oxide (ZnO) varistors is a well known, relatively
straightforward process in which ZnO grains are doped with cobalt,
bismuth, manganese and other oxides. The resulting grains have a Schottky
barrier at the grain interface and a typical grain breakdown voltage (Vb) of
approximately 3.6V per grain.
Currently, there are two types of varistors. Single layer varistors (SLVs) – an
older technology referred to as “pressed pill,” typically are larger, radial leaded
(MLVs) are a relatively new technology packaged in true EIA SMT case sizes.
Beyond the ZnO material system and grain breakdown similarity, MLVs and
SLVs have little in common. That is, to design a low voltage SLV, the grains
must be grown as large as possible to achieve a physically large enough part
obtain a consistent grain size in a low voltage SLV process.
The electrical performance of SLV is affected by inconsistent grain size
in two ways. First, low voltage SLVs often exhibit an inconsistent Vb and
leakage current (IL) from device to device within a particular manufacturing
lot of a given rating. This contributes to early high voltage repetitive strike
wear out.
Secondly, SLVs with similar voltage and energy ratings as MLVs typically
exhibit a lower peak current capability due in part to increased resistance of
the long current path of the large grains. This contributes to early repetitive
high current wear out.
At higher voltages, the grain size variations within SLVs play a much smaller
percentage role in Vb and leakage current values. As a result, SLVs are the
(e.g., 115 VAC, 220 VAC).

MLV MANUFACTURE
The construction of a MLV was made possible by employing a variety of
advanced multilayer chip capacitors (MLCC) manufacturing schemes
coupled with a variety of novel and proprietary ZnO manufacturing steps. In
the MLCC process, thin dielectrics are commonly employed to obtain very
large capacitance values. It is that capability to design and manufacture
to be easily made with operating/ working voltages (Vwm) as low as 3.3V
(for use in next generation silicon devices).
Once a particular working voltage has been determined (by altering the ZnO
dielectric thickness), the multilayer varistor’s transient energy capability
is determined by the number of layers of dielectric and electrodes. It is,
therefore, generally easy to control the grain size and uniformity within a MLV
due to the relative simplicity of this process.
MLVs exhibit capacitance due to their multiple electrode design and the
fact that ZnO is a ceramic dielectric. This capacitance can be utilized with
equivalent model of a MLV is shown in Figure 2.
MLVs are primarily used as transient voltage suppressors. In their “on” state,
they act as a back-to-back Zener, diverting to ground any excess, unwanted
energy above their clamping voltage. In their “off” state, they act as an EMC
capacitor (capacitance can be minimized for high speed applications). A
single MLV, therefore, can replace the diode, capacitor and resistor array on
multiplex node applications.
Any TVS will see a large number of transient strikes over its lifetime. These
transient strikes will result from different events such as well known ESD
random events. It is because of the repetitive strikes that all TVS suppressors
should be tested for multiple strike capability. Typically, a TVS will fail due to
high voltage, high current or over-energy strikes.
High voltage repetitive strikes are best represented by IEC 61000-4-2 8kV
waveforms. MLVs demonstrate a greatly superior capability to withstand
repetitive ESD high voltage discharge without degradation.
A comparison between MLVs, SLVs and SiTVS is shown in Figures 3A, B, C
respectively.
SILICON TVS MANUFACTURE
The construction of a silicon TVS departs dramatically from that of either
single layer varistor or multilayer varistor construction. Devices are generally
produced as Zener diodes with the exception that a larger junction area is
designed into the parts and additional testing was likely performed. After
the silicon die is processed in accordance to standard semi-conductor
manufacturing practice, the TVS die is connected to a heavy metal lead
MLVS COMPARED TO DIODES
The response time for a silicon diode die is truly sub-nanosecond. The lead
frame into which the die is placed and the wire bonds used for die connections
packaging causes a series impedance that slows the response time of
SiTVS devices. A best case response time of 8nS on SOT23 and a 1.5nS to
5nS response time on SMB and SMC products respectively are rather typical.
MLVs turn on time is <7nS. MLVs turn on time is faster than SiTVS and that
fast turn on time diverts more energy and current away from the IC than any
other protection device available.
CONCLUSION
The technology to manufacture MLVs exists and allows the manufacture of
miniature SMT surge suppressors. MLVs do not have the wear out failure
reliability numbers than that of TVS diodes. MLVs are a viable protection
device for auto multiplex bus applications.

AVX Multilayer Varistors – Assembly Guidelines
HANDLING
MLVs should be handled with care to avoid damage or contamination from
perspiration and skin oils. The use of tweezers or vacuum pickups is strongly
recommended for individual components. Bulk handling should ensure that
abrasion and mechanical shock are minimized. Taped and reeled components
provide the ideal medium for direct presentation to the placement machine.
PREHEAT
It is important to avoid the possibility of thermal shock during soldering and
carefully controlled preheat is therefore required. The rate of preheat should

give a good joint should be used. Excessive solder can lead to damage from
solder, chip and substrate. AVX terminations are suitable for all wave and
technique is the utilization of hot air soldering tools.
COOLING
Natural cooling in air is preferred, as this minimizes stresses within the
soldered joint. When forced air cooling is used, cooling rate should not
exceed 4°C/second.
CLEANING
Flux residues may be hygroscopic or acidic and must be removed. AVX MLVs
MIL-STD-202 and EIA-RS-198. Alcohol-based solvents are acceptable and
properly controlled water cleaning systems are also acceptable. Many other
solvents have been proven successful, and most solvents that are acceptable
to other components on circuit assemblies are equally acceptable for use
with MLVs.
POST SOLDER HANDLING
PCB applies stresses to the soldered joints of the components. For leaded
devices, the stresses are absorbed by the compliancy of the metal leads
and generally don’t result in problems unless the stress is large enough to
fracture the soldered connection.
Surface mount devices are more susceptible to such stress because they
don’t have compliant leads and are brittle in nature. The most frequent failure
loss of capacitance due to severing of contact between sets of internal
electrodes may be observed.

Type A:

REWORKING ASSEMBLIES
Thermal shock is common in MLVs that are manually attached or reworked
with a soldering iron. AVX strongly recommends that any reworking of MLVs
Direct contact by the soldering iron tip often causes thermal cracks that may
fail at a later date. If rework by soldering iron is absolutely necessary, it is
recommended that the wattage of the iron be less than 30 watts and the tip
temperature be <300°C. Rework should be performed by applying the solder
iron tip to the pad and not directly contacting any part of the component.
VARISTOR SOLDERABILITY
Historically, the solderability of Multilayer Varistors (MLVs) has been a
problem for the electronics manufacturer. He was faced with a device
that either did not wet as well as other electronic components, or had its
termination material leached away during the assembly process. However,
by utilizing proprietary procedures, AVX Corporation provides the market
with a MLV that has solderability comparable to that of other electronic
components, and resists leaching during assembly.
BACKGROUND
The basic construction of an unplated MLV is presented in Figure 1. The
external termination is a metal that connects the internal electrodes to
the circuitry of the assembly using the MLV. The external electrode must
solder used in assembly to wet the end of the chip and make a reliable
connection to the traces on the circuit board. Second, it must be robust
enough to withstand the assembly process. This is particularly important
if wave soldering is used. Unfortunately these two goals are competing. In
order to achieve good solderability, an alloy high in silver content is chosen.
However, this alloy is prone to leaching during assembly, so an additional
metal is added to improve the leach resistance. While this improves the
leach resistance, this addition makes the termination less solderable. The
results are either terminations that leach away, or do not solder well (see the
photographs in Figure 2).
Clearly, a plated termination system (as seen in Figure 3) is desired. This
system, which is typical of other electronic components such as capacitors
and resistors, produces a much better assembled product.

AVX Multilayer Varistors – Assembly Guidelines
In the plated termination, the base termination layer is still used (it
provides contact from the electrodes to the circuitry). On top of the base
termination is a layer of nickel. This is the surface to which the solder
bonds during assembly. It must be thick enough to stay intact during IR
away. It must also be thick enough to prevent the inter-metallic layer
the solderability.
In order to protect the nickel (i.e., maintain its solderability), a layer of
solder is plated on top of the nickel. The solder preserves the solderability
of the nickel layer. It must be thick and dense to keep oxygen and water
from reaching the nickel layer.
THE CHALLENGE
Zinc oxide varistors are semi-conductive in nature – that is what
allows them to “turn on” and divert a damaging transient away from
sensitive electronic circuitry and safely to ground. This semi-conduction
poses a major problem for the manufacturer that wants to plate the
terminations – the ceramic plates also! This condition, overplating,
must be controlled, as it is cosmetically undesirable and could result in
an unwanted path of conduction across the chip.
Early efforts in plating MLVs revolved around limiting the time that the
chip was in the plating bath. This helped prevent overplating, but also
produced chips with marginal solderability. The photographs in Figure
4 depict the problems that occur when the plated layers are not thick
enough.
THE SOLUTION
AVX has developed a proprietary process that passivates the ceramic
surface of the MLV. This allows us to plate the parts for a longer time
of nickel and alloy plated onto the base termination. These thicker
layers translate into bond strengths that are typically twice those of
solderability (as seen in Figure 5).
