The onsemi MCR218-004 is a standard recovery Silicon Controlled Rectifier (SCR) designed for various industrial applications, including power control and switching circuits. Featuring a voltage rating of 200V and an on-state current of 8A (RMS), this component is housed in a TO-220AB package for through-hole mounting. Key electrical specifications include a gate trigger current (Igt) of 25mA maximum and a holding current (Ih) of 30mA maximum. The device exhibits a low off-state leakage current of 10µA maximum and a peak surge current capability of 100A at 60Hz. With an on-state voltage drop (Vtm) of 1.8V maximum, it operates within a temperature range of -40°C to 125°C. This component is suitable for applications requiring efficient power switching and control.
