Littelfuse Inc. S4010FS21 is a sensitive gate Silicon Controlled Rectifier (SCR) designed for through-hole mounting in a TO-202 package with a short tab. This component offers a repetitive peak off-state voltage (VDRM) of 400V and an average on-state current (IT(AV)) of 6.4A, with an RMS on-state current (IT(RMS)) of 10A. Its sensitive gate characteristic is defined by a maximum gate trigger current (IGT) of 200 µA and a maximum gate trigger voltage (VGT) of 800 mV. The device exhibits a maximum holding current (IH) of 6 mA and a low off-state leakage current (IDRM) of 5 µA. Non-repetitive surge current capabilities are rated at 83A and 100A for 50Hz and 60Hz respectively. Operating temperature ranges from -40°C to 110°C. Applications include power control and switching circuits in industrial automation and appliance control systems.
