The onsemi MCR72-6T is an 8A, 400V sensitive gate Silicon Controlled Rectifier (SCR) housed in a TO-220AB package. This through-hole component features a maximum gate trigger current (Igt) of 200 µA and a gate trigger voltage (Vgt) of 1.5 V, indicating its suitability for applications requiring low-power triggering. The SCR exhibits a maximum on-state voltage (Vtm) of 2 V and an off-state current of 10 µA. With a non-repetitive surge current rating of 100A at 60Hz, it offers robust performance under transient conditions. The operating temperature range is -40°C to 110°C. This component is commonly utilized in industrial controls, power switching, and lighting control systems.
