Littelfuse Inc. T107B1 is a sensitive gate Silicon Controlled Rectifier (SCR) with a 200V blocking voltage and 4A RMS on-state current handling capability. Featuring a low gate trigger current (Igt) of 500 µA, this component is suitable for applications requiring precise triggering. The device exhibits a maximum on-state voltage (Vtm) of 2.5V and a holding current (Ih) of 6 mA. It offers a non-repetitive surge current rating of 16A at 50Hz and 20A at 60Hz. The T107B1 is housed in a TO-202 package with a long tab for through-hole mounting and operates within a temperature range of -40°C to 110°C. This SCR is commonly utilized in power control, lighting, and motor drive circuits.
