Motorola Thyristor Device Data is a data document about Motorola's thyristor devices. The document describes the features and applications of reverse blocking thyristors, such as motor controls, heating controls, and power supply crowbar circuits. The device has glass passivated junctions with center gate fire for greater parameter uniformity and stability. It is small, rugged, thermowatt constructed for low thermal resistance, high heat dissipation, and durability. It has a blocking voltage up to 800 volts and a surge current capability of 80 amps. The insulated package simplifies mounting.
This document provides technical data for the Motorola MCR218FP Series Reverse Blocking Thyristors, designed primarily for half-wave AC control applications such as motor controls, heating controls, and power supply crowbar circuits. The devices feature glass passivated junctions with center gate fire for parameter uniformity and stability, housed in a small, rugged thermowatt package.
