Glass Encapsulated TransGuard

®

Automotive Series

Multilayer Varistors for Automotive Applications

GENERAL DESCRIPTION

The Glass Encapsulated TransGuard

zinc oxide (ZnO) based ceramic semiconductor devices with

non-linear, bi-directional voltage-current characteristics.

They have the advantage of offering bi-directional

overvoltage protection as well as EMI/RFI attenuation in a

single SMT package. The Automotive Series high current

and high energy handling capability make them well suited

for protection against automotive related transients.

These large case size parts extend TransGuard range into

high energy applications. In addition the glass encapsulation

provides enhanced resistance against harsh environment or

process such as acidic environment, salts or chlorite flux.
