TransGuard® Mulitlayer Varistors

KYOCERA AVX TransGuard® Multilayer Varistors provide a wide range of reliable SMT components for bidirectional overvoltage protection with the advantage of EMI/RFI attenuation in the off-state for professional, industrial, and commercial applications. TransGuard MLVs are zinc oxide (ZnO) based ceramic semiconductor devices with non-linear voltage-current characteristics (bi-directional) similar to back-to-back Zener diodes. These KYOCERA AVX MLVs have the added advantage of more significant current and energy handling capabilities, speedy turn-on time, multiple strikes capability, and EMI/RFI attenuation in the off-state.

AntennaGuard Varistors

KYOCERA AVX AntennaGuard Varistors are a single-chip option for low capacitance varistors and feature small TVS components, standard EIA chip sizes, and fast response time to ESD strikes. The 0402/0603 size is available in capacitance values of ≤3pF and ≤12pF. Applications include laser drivers and ESD protection for RF amplifiers. The AntennaGuard/SPV varistors are offered in a low profile 0402 case size with ultra-low capacitance ESD protection, high reliability, low insertion loss, and bidirectional protection. Applications for KYOCERA AVX AntennaGuard Varistors include antennas, optics, HDMI, and RF circuits.

Automotive EV/HEV Solutions

KYOCERA AVX Automotive EV / HEV Solutions covers a range of applications, including power conversion, advanced driver-assistance systems (ADAS), lighting, active body control, and powertrain. These EV / HEV electronics face unique design challenges regarding communication, circuit protection, and higher operating voltages compared to traditional automotive electronics.

High-Temperature Automotive Varistors

KYOCERA AVX High-Temperature Automotive Varistors offer bidirectional protection and are AEC-Q200 qualified. The VTA AEC-Q200-qualified multilayer varistors allow designers to combine the circuit protection and EMI/RFI attenuation function into a single highly reliable device. The VTA series is tested, qualified, and specified for temperatures up to +175°C with no derating, and offers varistors with FLEXITERM® technology that provides up to 5mm of flexure without internal cracking. The VGAH series features a +150°C maximum temperature and is available in larger sizes than the VT series. The VGAH varistors are glass-encapsulated, providing enhanced resistance against harsh environments.
