Littelfuse Inc. TCR22-4RP is a sensitive gate Silicon Controlled Rectifier designed for through-hole mounting. This SCR features a 200V repetitive peak off-state voltage and a 1.5A RMS on-state current capability. The device exhibits a low gate trigger current of 200 µA maximum, enabling control with low-power logic signals. It maintains a holding current of 5 mA maximum and an off-state leakage current of 1 µA maximum. With a peak non-repetitive surge current rating of 20A at 60Hz, it offers robust performance in demanding applications. The TO-92 package is supplied on tape and reel, suitable for automated assembly. This component finds utility in various power control and switching applications across industrial and consumer electronics.
