What are the typical end products that require protection from this damage? What are the characteristics required of the circuit protection technology? Which circuit protection technologies best serve these types of situations? Overcurrent / Ground Faults Systems that are grounded and/or in near proximity to AC power lines Proper interrupting rating, current carrying capability and voltage rating Fuses and/or PTCs Lightning Any electronic or electrical equipment with connections to the outside environment Fast response, proper switching threshold, surge current rating SIDACtor(R) Protection Thyristors, Varistors (MOVs), TVS Diodes, Gas Discharge Tubes (GDTs) Electrostatic Discharge (ESD) Any electronic equipment with a human interface Fast response, high peak voltage rating PulseGuard(R) ESD Suppressors, SPATM Silicon Protection Arrays, Multi-Layer Varistors (MLVs) PLED LED Protectors Electrical Fast Transients (EFT) Any system that has inductive loads Fast rise time and recovery for repetitive pulses TVS Diodes, Varistors (MLVs and MOVs) PLED LED Protectors Inductive Load Switching and Commutative Spikes Large motors, pumps, compressors, relays and AC distribution High energy rating Varistors (MOVs and MLVs), GDTs, TVS Diodes Data and Communication Line Voltage Transients Ethernet, xDSL, data bus, telecom, etc. Fast response, low load capacitance SPATM Silicon Protection Arrays, SIDACtor(R) Protection Thyristors Current Switching / Diversion Wide range of electrical and electronic circuits Proper blocking voltage and current carrying capacity Switching Thyristors PLED LED Protectors OVERCURRENT EVENTS VOLTAGE TRANSIENT EVENTS Excessive current events can lead to catastrophic failures in electronic circuits. These failures can result in safety hazards such as fire, shock, or explosion. Common types of overcurrent threats include: Voltage transients are short duration surges or spikes. Unsuppressed, they may damage circuits and components, and result in complete system failure. Below are descriptions of common types of voltage transients, and technologies to reduce their effects: Overload Electrostatic Discharge (ESD) Overloads occur when more current is allowed to flow through a circuit path than it was designed to carry. This excess current can generate and accumulate heat and result in complete circuit destruction and possible fire, electrocution or explosion. Sources of overload can include: Damage from ESD is generally caused by the transfer of static electrical charge from a body to an electronic circuit. It may result in faulty circuit operation, latent defects, and even catastrophic failure of sensitive components. ESD suppressors must have very fast response times and handle high peak voltages and currents for short durations. Littelfuse offers a range of PulseGuard(R) ESD suppressors, Multi-Layer Varistors (MLVs) and SPATM Silicon Protection Array products designed to suppress these types of events (see page 16). * Construction hazards cutting across power mains * Equipment failure in the power grid * Environmental hazards on the power grid * Short spikes of energy within the circuit as a result of turning equipment on or off Inductive Load Switching Short circuits occur when one conducting path comes in contact with another conducting path or with ground, such as may occur due to a loose wire, insulation breakdown, or contact with water. These conditions can increase the likelihood of arcs, shock, or fire hazards. Switching of inductive loads, such as those that occur with transformers, generators, motors, and relays, can create transients up to hundreds of volts and amps, and can last as long as 400 milliseconds, affecting both AC and DC circuits. For these applications, commonly used suppressor devices include Metal Oxide Varistors (MOVs), Gas Discharge Tubes (GDTs), and Transient Voltage Suppression (TVS) Diodes. The principal forms of protection against overcurrent conditions include fuses and resettable positive temperature coefficient (PTC) thermistors. Lightning Induced Transient Short Circuit Their function is to limit current to acceptable levels and prevent catastrophic events, and during acceptable conditions act dormant with a minimal amount of resistance to the circuit. Fuses will completely stop the flow of current when opened, which may be desired with sensitive, expensive or critical applications. PTCs offer the ability to re-set for withstanding most minor, common and recurring overcurrent events. They will allow safe levels of current to pass continuously, and during major overcurrent events, increase in resistance as they heat, to restrict the flow of current. When the overcurrent event ends, the device resets to its normal operating state. Most transients induced by nearby lightning strikes result in an electromagnetic disturbance on electrical and communication lines connected to electronic equipment. Devices that protect against these transients must have a fast response time and must be able to dissipate a large amount of energy. Littelfuse Metal Oxide Varistor (MOV), TVS Diode and GDT products are typically used to protect against these events. Look to Littelfuse SIDACtor (R) and SPATM products for Telecom/Datacom requirements (see page 8). Automotive Load Dump Load dump refers to what happens to the supply voltage in a vehicle when a load is removed. If a load is removed rapidly (such as when the battery is disconnected while the engine is running), the voltage may spike before stabilizing and damage electronic components. In a typical 12V circuit, load dump can rise as high as 120V and take 400 ms to decay--more than enough to cause serious damage. Littelfuse offers a wide range of TVS Diode and Multi-Layer Varistor (MLV) products designed to protect against these types of events. 3 Common Circuit Threats www.littelfuse.com/designsupport Littelfuse Circuit Protection Technologies Technology Key Features and Protection Characteristics When / Where Typically Used Surge Energy Rating Range Typical Voltage Clamping Speeds Typical Capacitance/ Insertion Loss Mounting/ Size/ Packaging Options Overcurrent Protection Technologies: Fuses Completely stop current flow, which helps to identify faults; Wide range of options Ultimate protection for sensitive/ expensive/critical components Low thru Very High Not applicable Series impedance measured in nH Very Extensive Range of Options PTCs Resettable; No device replacement after most common overcurrent events Where overcurrent events may occur often, and continuous uptime desired Low thru High Not applicable Series resistance measured in ohms Surface Mount, Radial Leaded, Axial Strap Overvoltage Suppression Technologies: GDTs Switches that turn to on state and shunt overvoltage to ground using a contained inert gas as an insulator Protection of telecom equipment from lightning surges Medium thru High Fast Low Surface Mount, Axial Leaded, 2/3 Lead Radial Multi-Layer Varistors (MLVs) Compact and capable of handling significant surges for their size ESD and EFT suppression in smaller and portable electronics Low thru Medium Moderate High Miniature Surface Mount Metal-Oxide Varistor (MOVs) Capable of withstanding very high energy transients; Wide range of options Appliance, industrial and very high energy suppression applications Medium thru Very High Moderate High Radial Leaded, Industrial Terminal PLED LED Protectors Shunt function bypasses open LEDs; ESD and reverse power protection High brightness outdoor LED lighting applications Low Very Fast Medium Miniature Surface Mount PulseGuard(R) ESD Suppressors Extremely low capacitance; Fast response time; Compact size ESD suppression; Ultra fast reaction; Low signal distortion Low Moderate Low Miniature Surface Mount SPATM Silicon Protection Arrays Low capacitance / low clamping voltage; Compact size ESD suppression; Low distortion; Ideal for I/O interfaces and digital & analog signal lines Low thru Medium Very Fast Low Extensive range of surface mount options TVS Diodes Fast response to fast transients; Wide range of options Semiconductor protection; telecom I/O interfaces, electronics, industrial equipment Medium thru High Fast High Axial Leaded, Radial Leaded SIDACtor(R) Protection Thyristors Specifically designed to serve stringent telecom/ networking standards Telecom and networking applications Medium thru High Very Fast Low Extensive range of surface mount and thru-hole options Home appliances, power tools, outdoor equipment Not applicable Not applicable Not applicable Extensive range of surface mount and thru-hole options Switching Technologies: Power Thyristors 4 Solid state switches that switch to low "on" state and control the flow of current OVERVOLTAGE SUPPRESSION TECHNOLOGIES (1-6) 1.

They have high insulation resistance plus low capacitance and leakage to ensure minimal effect on normal operation of equipment. Littelfuse devices offer a small footprint and are available in leaded and surface mount configurations, with high surge handling capability. Their fast response to transient over-voltage events, and ability to dissipate large amounts of energy, translates into reduced risk of equipment damage. The amount of energy they can dissipate makes them a good choice for lightning surge protection, particularly for telecomm equipment located in outdoor structures.

Each provide distinct attributes for compatibility to specific circuit requirements. PulseGuard(R) ESD Suppressors offer extremely low capacitance for use in high-speed data circuits (IEEE 1394, USB 2.0, HDMI, DVI, etc.). Available in single-line and multi-line packages, they provide ESD protection while ensuring that signal integrity is maintained. SPATM Silicon Protection Arrays offer a high level of protection (up to 30kV per IEC 61000-4-2) with very low capacitance, leakage current and clamp voltage. For more robust applications, SP03-xx and SP30xx devices are available for EFT and Lightning transient threats per IEC-61000-4-4/5. Multi-Layer Varistors (MLVs) provide board level protection against ESD, EFT, and other transients that occur on power supply, data and control lines. Single ThroughHole Series Name Surface Mount line devices are available in popular industry standard formats, and for more efficient board space usage, four-line devices are also available.

Designed to minimize the impact of loss of an entire string of LEDs due to a single LED failure, PLED devices provide a switching function that will bypass LEDs that go open circuit, and allow current to flow to the remaining LEDs in the string. PLED devices also offer LED protection against electrostatic discharge (ESD) and accidental reverse power connection (PLED5 devices only). Designed to serve the needs of high brightness outdoor LED lighting applications (advertising and traffic signs, roadway/pathway/runway lighting, aircraft and emergency lighting, etc), PLED devices help assure reliability and lower maintenance requirements.
