TISP3xxxH3SL Overview
Summary Electrical Characteristics
This TISP® device series protects central office, access and customer premise equipment against overvoltages on the telecom line. The
TISP3xxxH3SL protects R-G and T-G. In addition, the device is rated for simultaneous R-G and T-G impulse conditions. The TISP3xxxH3SL is
available in a wide range of voltages and has a high current capability, allowing minimal series resistance to be used. These protectors have
been specified mindful of the following standards and recommendations: GR-1089-CORE, FCC Part 68, UL1950, EN 60950, IEC 60950, ITU-T
K.20, K.21 and K.45. The TISP3350H3SL meets the FCC Part 68 “B” ringer voltage requirement and survives both Type A and B impulse tests.
These devices are housed in a through-hole 3-pin single-in-line (SL) plastic package.

SL Package (Top View)
TISP3xxxH3SL Overvoltage Protector Series
Rated for International Surge Wave Shapes
- Single and Simultaneous Impulses
The TISP3xxxH3SL limits overvoltages between the telephone line Ring and Tip conductors and Ground. Overvoltages are normally caused by
a.c. power system or lightning flash disturbances which are induced or conducted on to the telephone line.
The protector consists of two symmetrical voltage-triggered bidirectional thyristors. Overvoltages are initially clipped by breakdown clamping
until the voltage rises to the breakover level, which causes the device to crowbar into a low-voltage on state. This low-voltage on state causes
the current resulting from the overvoltage to be safely diverted through the device. The high crowbar holding current prevents d.c. latchup as
the diverted current subsides.
This TISP3xxxH3SL range consists of twelve voltage variants to meet various maximum system voltage levels (58 V to 275 V). They are
guaranteed to voltage limit and withstand the listed international lightning surges in both polarities. These high current protection devices are in
a 3-pin single-in-line (SL) plastic package and are supplied in tube pack. For alternative impulse rating, voltage and holding current values in
SL packaged protectors, consult the factory. For lower rated impulse currents in the SL package, the 35 A 10/1000 TISP3xxxF3SL series is
available. These monolithic protection devices are fabricated in ion-implanted planar structures to ensure precise and matched breakover
control and are virtually transparent to the system in normal operation.

APPLICATIONS INFORMATION
AC Power Testing
Capacitance
Normal System Voltage Levels
To verify the withstand capability and safety of the equipment, standards require that the equipment is tested with various impulse wave forms.
The table below shows some common values.
If the impulse generator current exceeds the protector’s current rating, then a series resistance can be used to reduce the current to the
protector’s rated value to prevent possible failure. The required value of series resistance for a given waveform is given by the following
calculations. First, the minimum total circuit impedance is found by dividing the impulse generator’s peak voltage by the protector’s rated
current. The impulse generator’s fictitious impedance (generator’s peak voltage divided by peak short circuit current) is then subtracted from
the minimum total circuit impedance to give the required value of series resistance. In some cases, the equipment will require verification over
a temperature range. By using the rated waveform values from Figure 10, the appropriate series resistor value can be calculated for ambient
temperatures in the range of -40 °C to 85 °C.
The protector can withstand the G return currents applied for times not exceeding those shown in Figure 8. Currents that exceed these times
must be terminated or reduced to avoid protector failure. Fuses, PTC (Positive Temperature Coefficient) resistors and fusible resistors are
overcurrent protection devices which can be used to reduce the current flow. Protective fuses may range from a few hundred milliamperes to
one ampere. In some cases, it may be necessary to add some extra series resistance to prevent the fuse opening during impulse testing. The
current versus time characteristic of the overcurrent protector must be below the line shown in Figure 8. In some cases, there may be a further
time limit imposed by the test standard (e.g. UL 1459 wiring simulator failure).
The protector characteristic off-state capacitance values are given for d.c. bias voltage, VD, values of 0, -1 V, -2 V, and -50 V. Where possible,
values are also given for -100 V. Values for other voltages may be calculated by multiplying the VD = 0 capacitance value by the factor given in
Figure 6. Up to 10 MHz, the capacitance is essentially independent of frequency. Above 10 MHz, the effective capacitance is strongly
dependent on connection inductance. In many applications, the typical conductor bias voltages will be about -2 V and -50 V. Figure 7 shows
the differential (line unbalance) capacitance caused by biasing one protector at -2 V and the other at -50 V.
The protector should not clip or limit the voltages that occur in normal system operation. For unusual conditions, such as ringing without the
line connected, some degree of clipping is permissible. Under this condition, about 10 V of clipping is normally possible without activating the
ring trip circuit. Figure 9 allows the calculation of the protector VDRM value at temperatures below 25 °C. The calculated value should not
be less than the maximum normal system voltages. The TISP3290H3, with a VDRM of 220 V, can be used for the protection of ring generators
producing 105 V rms of ring on a battery voltage of -58 V. The peak ring voltage will be 58 + 1.414*105 = 206.5 V. However, this is the open
circuit voltage and the connection of the line and its equipment will reduce the peak voltage.

APPLICATIONS INFORMATION
For the extreme case of an unconnected line, the temperature at which clipping begins can be calculated using the data from Figure 9. To
possibly clip, the VDRM value has to be 206.5 V. This is a reduction of the 220 V 25 °C VDRM value by a factor of 206.5/220 = 0.94. Figure 9
shows that a 0.94 reduction will occur at an ambient temperature of -32 °C. In this example, the TISP3290H3 will allow normal equipment
operation, even on an open-circuit line, provided that the minimum expected ambient temperature does not fall below -32 °C.
JESD51 Thermal Measurement Method
To standardize thermal measurements, the EIA (Electronic Industries Alliance) has created the JESD51 standard. Part 2 of the standard
(JESD51-2, 1995) describes the test environment. This is a 0.0283 m3 (1 ft3) cube which contains the test PCB (Printed Circuit Board)
horizontally mounted at the center. Part 3 of the standard (JESD51-3, 1996) defines two test PCBs for surface mount components; one for
packages smaller than 27 mm (1.06 ”) on a side and the other for packages up to 48 mm (1.89 ”). The thermal measurements used the smaller
76.2 mm x 114.3 mm (3.0 ” x 4.5 ”) PCB. The JESD51-3 PCBs are designed to have low effective thermal conductivity (high thermal resistance)
and represent a worse case condition. The PCBs used in the majority of applications will achieve lower values of thermal resistance and so
can dissipate higher power levels than indicated by the JESD51 values.
