The onsemi MCR708AT4 is a sensitive gate Silicon Controlled Rectifier (SCR) designed for high-reliability applications. This component features a 600V blocking voltage and a 4A RMS on-state current capability. Its sensitive gate requires a maximum trigger current (Igt) of 75 µA and a gate voltage (Vgt) of 800 mV for turn-on. The device maintains a holding current (Ih) of 5 mA, ensuring stable operation. With a non-repetitive surge current rating of 25A at 60Hz, it offers robust performance under transient conditions. The MCR708AT4 is available in a TO-252-3, DPAK package for efficient surface mounting and is supplied in cut tape. This SCR is commonly utilized in power control, lighting control, and motor drive applications within the industrial and automotive sectors.
