The UTC MCR101 SCR is a PNPN device designed for high volume, line-powered consumer applications such as relay and lamp drivers, small motor controls, gate drivers for larger thyristors, and sensing and detection circuits. It features a sensitive gate that allows triggering by microcontrollers and other logic circuits, a blocking voltage of up to 600V, an on-state current rating of 0.8A RMS at 80°C, high surge current capability of 10A, and immunity to dV/dt of at least 20V/µsec at 110°C.
The document describes the UTC MCR101, a sensitive gate silicon controlled rectifier (SCR) designed for high-volume line-powered consumer applications such as relay drivers, lamp controls, and motor control circuits. The device is supplied in an inexpensive plastic TO-92 package suitable for automatic insertion equipment.
