Varistor Characteristics and Equivalent Circuit

ESD Suppressive Effects

Replacement of Zener diode

A Multilayer Varistor does not have an electrical polarity like zener diodes and is equivalent to total 3 pcs.

of 2 zener diodes and 1 capacitor.

[Equivalent Circuit]

[ESD suppressed waveform]

Typical effects of ESD suppression

Replacing “Zener diode and Capacitor” with Multilayer Varistor saves both the mounting area and number

of components used.
