Littelfuse Inc. S4008FS24 is a sensitive gate Silicon Controlled Rectifier (SCR) designed for through-hole mounting. This component features a repetitive peak off-state voltage (VDRM) of 400V and an average on-state current (IT(AV)) of 5.1A, with an RMS on-state current (IT(RMS)) rating of 8A. The maximum on-state voltage (VTM) is 1.6V. Key parameters include a low gate trigger current (IGT) of 200 µA and a gate trigger voltage (VGT) of 800 mV, facilitating triggering with minimal gate current. The device exhibits a holding current (IH) of 6 mA and a low off-state leakage current (IDRM) of 5 µA. Non-repetitive surge current handling is 83A and 100A at 50Hz and 60Hz respectively. The TO-202 package with a short tab ensures efficient heat dissipation. This SCR is suitable for applications in power control, lighting control, and motor speed regulation across industrial and consumer electronics sectors. Operating temperature range is -40°C to 110°C.
