Littelfuse Inc. T106D2 is a sensitive gate Silicon Controlled Rectifier (SCR) designed for through-hole mounting in a TO-202 package. This component offers a 400V off-state voltage rating and a continuous on-state current capability of 2.5A (average) and 4A (RMS). It features a low gate trigger current of 200 µA (max) and a gate trigger voltage of 800 mV (max), facilitating activation with minimal control signal. The SCR exhibits a hold current of 5 mA (max) and a low off-state leakage current of 2 µA (max). Non-repetitive surge current handling is rated at 16A and 20A for 50Hz and 60Hz respectively. Operating temperature ranges from -40°C to 110°C. This device is commonly utilized in power control applications across industrial automation, motor control, and lighting control systems.
