onsemi MCR718T4 is a sensitive gate Silicon Controlled Rectifier (SCR) designed for robust control applications. This component features a 600V off-state voltage and a 4A RMS on-state current rating, with an average on-state current of 2.6A. Its high surge capability of 25A at 60Hz ensures reliability under demanding conditions. The low gate trigger current requirement of 75 µA and a maximum gate trigger voltage of 800mV facilitate easy interface with low-power control circuitry. The MCR718T4 exhibits a maximum off-state current of 10 µA and a holding current of 5 mA. Operating within a temperature range of -40°C to 110°C, this SCR is housed in a TO-252-3, DPAK surface mount package, supplied on tape and reel. It is commonly utilized in power control systems and industrial automation.
