The Mitsubishi Electric / Powerex CM300DU-12H is a high-current 600 V, 300 A dual IGBT power module containing two power IGBTs arranged as a half-bridge. Each switching device incorporates a reverse-connected fast free-wheel diode, providing the current paths required for efficient operation with inductive loads in inverter, motor-drive, UPS, and industrial power-conversion systems.
The two-device configuration provides a complete inverter leg in one rugged module, reducing external high-current interconnections and simplifying busbar, heatsink, and service design. Its isolated baseplate allows the module to be mounted directly to a properly prepared heatsink while maintaining electrical isolation between the semiconductor circuit and cooling surface.
With a 300 A continuous-current class rating and substantial short-duration current capability, the CM300DU-12H is suited to demanding UPS inverter and rectifier stages, variable-frequency drives, industrial motor controls, welding equipment, DC choppers, and other high-power switching applications. It is also valuable as a replacement component in legacy power electronics where the original Mitsubishi module must be matched for voltage, current, circuit configuration, gate drive, terminal arrangement, and mechanical footprint.
