This document describes PNPN devices designed for line powered consumer applications such as relay and lamp drivers, small motor controls, gate drivers for larger thyristors, and sensing and detection circuits. The devices are supplied in surface mount package for use in automated manufacturing.
The MCR08B and MCR08M are reverse blocking thyristors (PNPN devices) designed for line powered consumer applications such as relay and lamp drivers, small motor controls, gate drivers for larger thyristors, and sensing and detection circuits. The datasheet lists a sensitive gate trigger current, blocking voltage to 600 volts, a glass passivated surface, and a surface mount package.
It provides maximum ratings, thermal characteristics, electrical characteristics, performance curves, and information for using the SOT-223 surface mount package, including power dissipation and solder stencil guidelines.
