The onsemi MCR8DSMT4 is a sensitive gate Silicon Controlled Rectifier (SCR) designed for surface mount applications. This component features a repetitive peak off-state voltage (VDRM) of 600V and an average on-state current (IT(AV)) of 5.1A, with a maximum RMS on-state current (IT(RMS)) of 8A. It exhibits a low gate trigger current (IGT) of 200 µA and a gate trigger voltage (VGT) of 1V, facilitating triggering with low-power control signals. The device boasts a non-repetitive surge current (ITSM) of 90A at 60Hz and a low off-state leakage current of 10 µA. Encased in a TO-252-3, DPAK package, the MCR8DSMT4 is suitable for operation across a temperature range of -40°C to 110°C. This SCR is commonly utilized in power control, motor drive, and lighting control applications within the industrial and consumer electronics sectors.
