Overview
(1/10) Varistors(SMD) Countermeasure for Surge and Static Electricity Conformity to RoHS Directive AVR Series AVR-M, AVRL Types Varistor (Variable resistor) is a nonlinear resistive element of the voltage dependence that resistance changes with applied voltage.
Varistor is equivalent with Zener diode of two series connection.
Therefore, do not have polarity.

004-01 / 20071227 / e9c11_avr.
fm (2/10) FEATURES • No polarity, due to symmetrical current-voltage characteristics.
Equivalent to anode common type Zener diode.
• Excellent electrostatic absorption capability.
Response is as good or better than Zener diode.
Keeps symmetrical current-voltage characteristics even after electrostatic absorption.
• Adopted the inner electrodes lamination structure.
Wide range of varistor voltages are available in series (8 to 39V).
Low capacitance items are available in series (3.
3pF to).
World’s smallest 0603-type, 1005-, 1608-, 2012-chip types and 1410-array type are available in series.
• Excellent mount reliability.
Good for Pb-free soldering.
Adopted (Ni/Sn) electroplating.
Achieved good solderability and solder heat resistance.
• Can replace a Zener diode + capacitor combination.
Reduced footprint and total mounting cost.
