PtC PRoduCts
PTCs (positive temperature coefficient) increase resistance as temperature increases. They are designed to prevent unsafe
levels of current while allowing constant safe current levels, and their resistance will “reset” automatically when the current and
temperature returns to a safe level. PTCs are typically used in applications where automatic reset is desired.

gdt PRoduCts
GDTs (gas discharge tube) dissipate voltage transients through a contained plasma gas. 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 telecom equipment located in outdoor structures.

Overvoltage Suppression Protection (continued)
tVs diodes
TVS Diodes are used to protect semiconductor components from high-voltage transients.Their p-n junctions have a larger cross-sectional
area than those of a normal diode, allowing them to conduct large currents to ground without sustaining damage. Littelfuse suppliesTVS
Diodes with peak power ratings from 200W to 30kW, and reverse standoff voltages from 5V to 512V.

PLed Light-eꢊittiNg diode (Led) PRoteCtoRs
Littelfuse PLED devices provide added reliability to LED lighting strings. Designed to minimize the impact of losing an entire
LED string 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 costs.

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:
ovꢁrlꢀaꢇ
elꢁcꢂrꢀꢄꢂaꢂꢅc dꢅꢄcꢃarꢆꢁ (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® ESD suppressors, Multi-Layer Varistors
(MLVs) and TVS Diode Array – SPA® Diodes that are
designed to suppress these types of events.
• 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
inꢇꢈcꢂꢅvꢁ Lꢀaꢇ swꢅꢂcꢃꢅnꢆ
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.
sꢃꢀrꢂ Cꢅrcꢈꢅꢂ
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.
The principal forms of protection against overcurrent
conditions include fuses and resettable positive
temperature coefficient (PTC) thermistors.
Lꢅꢆꢃꢂnꢅnꢆ inꢇꢈcꢁꢇ tranꢄꢅꢁnꢂ
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 Diodes and GDT products are
typically used to protect against these events. Look to
Littelfuse SIDACtor® Protection Thyristors and TVS Diode
Array – SPA® Diode products for Telecom/Datacom
requirements (see page 22).
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.

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.
