Introduction

The ZV series low-voltage varistors are designed to protect sensitive electronic equipment from high-voltage surges in low-voltage applications. They feature excellent transient energy absorption capability due to improved energy-volume distribution and power dissipation. The DC operating voltage range of low-voltage varistors is wide, spanning from 14V to 170V. The ZVY series is identical except that the maximum operating temperature reaches 150°C.

ZV varistors are commonly used to protect components at the PCB level.
