Glass Encapsulated TransGuard®
Automotive Series
GENERAL DESCRIPTION
The Glass Encapsulated TransGuard®Automotive Series are
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.
