Varistors are voltage dependent, nonlinear devices which have an electrical behavior similar to back-to-back zener diodes. The symmetrical, sharp breakdown characteristics enable the varistor to provide excellent transient suppression performance. When exposed to high voltage transients the varistor impedance changes many orders of magnitude from a near open circuit to a highly conductive level, thus clamping the transient voltage to a safe level. The potentially destructive energy of the incoming transient pulse is absorbed by the varistor, thereby protecting vulnerable circuit components.

Applications:

◇ Surge Protection in consumer electronics, such as:

* industrial electronics,
* telephone and telecommunication systems,
* sutomobile equipments,
* measuring and controller systems,
* electronic home appliances
* gas and petroleum appliances

◇ Absorption of switching surge from various kinds of relays and electro-magnetic valves.
◇ Electrostatic discharge an spike noise suppression.
◇ Protection of various kinds of transistors, diodes, ICs, tyristors, triac semiconductors and etc.
◇ Automobile control system such as transistorized ignition system and electronic fuel injection system, and etc.

Features:
◇ Fast response
◇ Excellent voltage ratio
◇ High stabilization for circuit voltage
◇ Unparalleled absorption for transient voltage characteristics
◇ Bilateral and symmetrical V-I Characteristics curve

Related Standards :
◇ UL1414, UL1449 (2ND Edition), CSA, VDE
