Littelfuse High-Temperature SCRs are ideal for uni-directional switch applications such as phase control in heating, motor speed controls, converters/rectifiers, and capacitive discharge ignitions. These SCRs have a low gate current trigger level of 200µA maximum at approximately 1.5V. Typical applications include capacitive discharge system for motorcycle engine CDI, portable generator engine ignition, strobe lights, nailers, and more.Learn More

SJ SCR Switching Thyristors
Littelfuse SJ Series SCR Switching Thyristors offer designers a wider operating margin than earlier SCRs, making it possible to tolerate insufficient cooling and higher inrush currents at startup. This Littelfuse SCR thyristor series provides a wider operating margin in existing designs and allows smaller heat sinks in new designs. The SJ Series features a robust clip-attach package design that withstands high surges in a choice of five package types. Littlefuse SJ series offers a high junction temperature (TJ) of 150°C, blocking voltage (VDRM) up to 600V, and current ratings from 4A up to 40A. These tyhristors offer a gate trigger current (IGT) of 0.2mA in sensitive gate SCR and between 6mA and 40mA in standard gate SCR.
