KYOCERA AVX CAN BUS Automotive Varistors

KYOCERA AVX CAN BUS Automotive Varistors are zinc oxide (ZnO) based ceramic semiconductor devices with nonlinear voltage-current characteristics (bidirectional). These varistors are similar to back-to-back Zener diodes and an EMC capacitor in parallel. KYOCERA AVX CAN0005 CAN BUS Automotive Varistors have the added advantage of greater current and energy handling capabilities as well as EMI/RFI attenuation. These 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.

The varistors provide a large in-rush current capability, low capacitance to minimize signal distortion, fast turn-on times 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 the KYOCERA AVX CAN BUS Automotive Varistors an ideal device for automotive or general circuit protection.
