Littelfuse Inc. SCR, part number TCR22-4, is a 200V, 1.5A sensitive gate silicon controlled rectifier. This through-hole component is packaged in a TO-92 (TO-226-3, TO-92-3) case. The TCR22-4 features a maximum gate trigger current (Igt) of 200 µA and a maximum gate trigger voltage (Vgt) of 800 mV. It exhibits a maximum off-state current of 1 µA and a maximum on-state voltage (Vtm) of 1.5 V. The device offers a sustained on-state current (It(AV)) of 950 mA and an RMS on-state current (It(RMS)) of 1.5 A. Non-repetitive surge current for 50/60Hz is rated at 16A and 20A respectively. Operating temperature ranges from -40°C to 110°C. This component is suitable for applications in industrial control, power switching, and lighting control systems.
