Littelfuse Inc. S2004VS2 is a sensitive gate Silicon Controlled Rectifier (SCR) designed for AC power control applications. This TO-251 packaged device offers a repetitive peak off-state voltage (VDRM) of 200V and an average on-state current (IT(AV)) of 2.5A, with an RMS on-state current rating of 4A. Its low gate trigger current (IGT) of 200 µA and gate trigger voltage (VGT) of 800 mV at 25°C make it suitable for applications requiring sensitive triggering. The device exhibits a low leakage current of 2 µA (IDRM) and a holding current (IH) of 6 mA. It can withstand non-repetitive surge currents of 25A and 30A for 50Hz and 60Hz respectively. The Littelfuse Inc. S2004VS2 is commonly utilized in industrial motor controls, lighting controls, and power supply switching. Operating temperature range is -40°C to 110°C.
