Littelfuse Inc. T106D1 is a sensitive gate Silicon Controlled Rectifier (SCR) designed for various power control applications. This through-hole component features a 400V off-state voltage and a 4A RMS on-state current rating. 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, facilitating easier triggering from low-power control sources. The device exhibits a low off-state leakage current of 2 µA and a hold current (Ih) of 5 mA. With a non-repetitive surge current rating of 16A and 20A at 50Hz and 60Hz respectively, it offers robust performance under transient conditions. The SCR is housed in a TO-202 package with a long tab and operates within a temperature range of -40°C to 110°C. This component is suitable for use in industrial control, power switching, and lighting applications.
