The onsemi MCR708A1 is a 600V, 4A Silicon Controlled Rectifier (SCR) designed for sensitive gate applications. This through-hole component, housed in an IPAK package (TO-251-3 Short Leads, TO-251AA), features a maximum on-state current of 1.6A (average) and 4A (RMS). It exhibits a low gate trigger current of 75 µA (maximum) and a gate trigger voltage of 800 mV (maximum). The off-state current is a maximum of 10 µA, with a hold current requirement of 5 mA (maximum). The MCR708A1 is rated for a non-repetitive surge current of 25A at 60Hz 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.
