Littelfuse Inc. T107D2 is a sensitive gate Silicon Controlled Rectifier (SCR) designed for through-hole mounting in a TO-202 package. This component features an off-state voltage rating of 400V and an RMS on-state current handling capability of 4A, with an average on-state current of 2.5A. The T107D2 exhibits a low gate trigger current (Igt) requirement of 500 µA maximum and a gate trigger voltage (Vgt) of 800 mV maximum, indicating enhanced sensitivity for triggering. It has a hold current (Ih) of 6 mA maximum and a minimal off-state current of 2 µA. The non-repetitive surge current (Itsm) is rated at 16A and 20A for 50Hz and 60Hz respectively. Operating temperature ranges from -40°C to 110°C. This SCR is commonly utilized in power control applications within industrial automation, consumer electronics, and lighting control systems.
