Communication BUS Varistor
GENERAL DESCRIPTION
The CAN BUS and FlexRay varistor is a zinc oxide (ZnO) based ceramic semiconductor device
with non-linear voltage-current characteristics (bi-directional) similar to back-to-back Zener
diodes and an EMC capacitor in parallel (see equivalent circuit model). They have the added
advantage of greater current and energy handling capabilities as well as EMI/RFI attenuation.
Devices are fabricated by a ceramic sintering process that yields a structure of conductive ZnO
grains surrounded by electrically insulating barriers, creating varistor like behavior.
