Communication BUS Varistor
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.
AVX Communication Bus Varistors offer the advantages of large in-rush current capability, low
capacitance to minimize signal distortion, fast turn on time to conservatively clamp the energy
before its maximum and off state EMI filtering through their bulk capacitance. These features
coupled with an extremely low FIT rate and excellent process capability make an ideal device for
today's automotive or general circuit protection.
