The MCR12M / MCR12N are Motorola thyristors designed primarily for half-wave AC control applications, such as motor controls, heating controls, and power supplies. They are rated for blocking voltages up to 800 volts, on-state currents up to 12 amperes, and peak surge currents up to 100 amperes. They are packaged in a standard TO-220AB package and have glass-passivated junctions for reliability and uniformity.
This document provides technical data for the Motorola MCR12 Series, which includes Silicon Controlled Rectifiers (SCRs) and Reverse Blocking Thyristors. These devices are designed primarily for half-wave AC control applications such as motor controls, heating controls, and power supplies. The series offers blocking voltages up to 800 Volts and an on-state current rating of 12 Amperes RMS.
