Half wave AC control silicon controlled rectifier Littelfuse MCR8SNG featuring 8A RMS and 800V blocking voltage
Product Overview
The MCR8SDG, MCR8SMG, and MCR8SNG are sensitive gate silicon controlled rectifiers designed for half-wave AC control applications. Their sensitive gate allows triggering by microcontrollers and other logic circuits. These devices offer blocking voltages up to 800V, an on-state current rating of 8A RMS at 80C, and high surge current capability. They are housed in a rugged, economical TO-220AB package with glass-passivated junctions for reliability. Designed for applications such as motor controls, heating controls, and power supplies where half-wave, silicon gate-controlled devices are needed. These are Pb-Free devices.
