Littelfuse Inc. S4003LS2 SCR, a sensitive gate silicon controlled rectifier, offers a 400V standoff voltage and a 3A RMS on-state current rating. This through-hole component, housed in a TO-220 isolated tab package, features a maximum gate trigger current (Igt) of 200 µA and a holding current (Ih) of 6 mA. The device exhibits a low leakage current of 2 µA and a peak non-repetitive surge current capability of 25A/30A. With an on-state voltage drop (Vtm) of 1.6V, the S4003LS2 is suitable for applications in industrial controls, power switching, and lighting control systems. It operates within a temperature range of -40°C to 110°C.
