CM300DY-24T
1200 V / 300 A Mitsubishi Electric T-series 2in1 dual IGBT module for large drives and industrial power supplies.
The CM300DY-24T is a 1200 V / 300 A Mitsubishi Electric IGBT module in the standard T-series package, configured as a 2in1 dual half-bridge with a 4000 Vrms isolation voltage. It carries a high current from one half-bridge leg, so three modules build a three-phase inverter for large motor drives, UPS and industrial power supplies where paralleling smaller devices would add complexity and current-sharing risk. The 1200 V class gives the margin a rectified 380 to 480 V AC bus needs, and the CSTBT chip structure and optimized package keep conduction and switching loss low while improving heat dissipation. The flat, insulated base mounts directly on a common heatsink and distributes heat evenly, and the module reduces the parts count, wiring and assembly time of the power stage. Every module is factory-traceable and ships with import declaration, certificate of origin and RoHS documentation. Because it is a high-current part, confirm busbar inductance, gate-drive strength and the thermal design with our FAE team before layout sign-off. BeiLuo holds this module in regional stock and supports gate-drive, layout and thermal design.
FAE Professional Review
The CM300DY-24T is the 1200 V dual we recommend when a leg must carry a few hundred amps. The flat base spreads heat well and the CSTBT chip keeps loss in check. At this current the busbar design and gate loop dominate, so get those right and it is a rugged, predictable module.

Frequently Asked Questions
What projects suit the CM300DY-24T?
It fits 1200 V inverters and converters in the hundreds-of-amps class such as large motor drives, UPS stages and industrial power supplies. Three dual modules build a three-phase bridge, so it is a flexible high-current building block.
For lower current, the CM100DY-24T is more economical.
What busbar and gate design do I need?
High current demands a low-inductance laminated busbar and a stiff, low-inductance gate loop. Keep the commutation loop tight and measure turn-off overvoltage at the module terminals, not at the bus.
Our FAE team can review your layout.
Is the module genuine and documented?
BeiLuo supplies factory-traceable CM300DY-24T modules through Mitsubishi Electric's authorized channel, with import declaration, certificate of origin and RoHS files on every order. Stock is normally available.
