Overview of the AVR series
CHARACTERISTICS OF CHIP VARISTOR
Varistors are voltage dependent nonlinear resistive elements with a resistance that decreases rapidly when the voltage is over the constant value. Varistors bee zener diode of 2 serial connection and equivalent, and does not have polarity.
