The PHYTVSxxxV4 series is a patent pending hybrid state-of-the-art semiconductor technology intended for AC power transient protection. This series is designed to protect critical industrial and consumer applications, where a reliable overvoltage soluion with lower clamping voltage is required. The PHYTVSxxxV4 series technology is an ideal replacement for surface mount Metal Oxide Varistors (MOV), offering a more robust product in a small form factor that does not present a wear-out mechanism that is common with MOVs, thus extending signficantly its operation lifetime.
