The CM400DY-12H is a high-current dual IGBT module from Mitsubishi Electric, one of the world's leading manufacturers of power semiconductor devices. Rated at 400 amperes and 600 volts, this module integrates two IGBT chips with co-packed freewheeling diodes in a robust package, offering excellent thermal performance and switching efficiency. Its rugged construction and proven reliability make it a preferred choice for engineers designing high-power industrial and commercial systems.

The CM400DY-12H is widely used in AC motor drives, industrial inverters, UPS systems, servo drives, welding equipment, and traction applications. Its dual configuration simplifies circuit design for half-bridge topologies commonly found in variable frequency drives (VFDs) and power conditioning systems where high current handling is critical.
