MCR218 is a bidirectional thyristor produced by Semiconductor Components Industries, LLC. It is mainly used for half-wave ac control applications such as motor controls, heating controls and power supplies, or wherever half-wave silicon gate-controlled, solid-state devices are needed.
This document provides technical specifications for the MCR218-2, MCR218-4, and MCR218-6 silicon controlled rectifiers (SCRs). These preferred devices are designed primarily for half-wave AC control applications, such as motor controls, heating controls, and power supplies. They feature glass-passivated junctions and TO-220 construction for low thermal resistance and high durability.
