Protect Next-Generation Automotive Electronics with KYOCERA AVX TransGuard® VT Series High-Temperature MLVs

Reliable Transient Protection for Harsh Automotive Environments

As vehicles become more connected, electrified, and automated, engineers face growing challenges in protecting increasingly sophisticated electronic systems. KYOCERA AVX TransGuard® VT Series High-Temperature Automotive Multilayer Varistors (MLVs) are designed to help safeguard sensitive automotive electronics from transient voltage events, electrostatic discharge (ESD), and other electrical stresses while delivering reliable performance in harsh, high-temperature environments.

Modern vehicles now contain hundreds of electronic control systems responsible for everything from safety and connectivity to power management and vehicle communication. These advanced systems rely on sensitive semiconductors that must operate reliably despite exposure to voltage transients, switching noise, ESD, and extreme operating temperatures.

For engineers, protecting these electronics while maintaining compact PCB layouts and meeting stringent automotive reliability requirements remains an ongoing design challenge.

The KYOCERA AVX TransGuard® VT Series addresses these challenges with compact multilayer ceramic varistor technology that combines fast response performance, high-temperature capability, and robust transient protection to help improve system reliability across demanding automotive applications.
