SETsafe | SETfuse SMDJ18CA

Transient Voltage Suppressor (TVS) is a circuit protection component that attenuates or filters transient voltage spikes (overvoltage). Upon a surge event, it undergoes avalanche breakdown within a few nanoseconds, redirecting the surge current to ground and clamping the voltage within a safe range, thereby delivering high-efficiency voltage protection.
