Mitsubishi CM300DY-12NF 300A 600V Dual IGBT Power Module

The Mitsubishi Electric CM300DY-12NF is a high-power dual IGBT module from the NF Series, designed for industrial power switching applications including general-purpose inverters, variable frequency drives, servo control systems, motor drives, UPS equipment, and industrial power-conversion systems.

The module integrates two high-power IGBT elements in a half-bridge configuration together with reverse-connected fast recovery free-wheel diodes. It is rated for a collector-emitter voltage of 600V and continuous collector current of 300A.

600V / 300A High-Power IGBT

The CM300DY-12NF has a maximum collector-emitter voltage rating of 600V and a continuous collector current rating of 300A under the specified thermal conditions. Pulse collector current is rated up to 600A, making the device suitable for demanding industrial switching applications when operated within the manufacturer's electrical and thermal limits.

Dual IGBT Half-Bridge Configuration

Two IGBT elements are integrated into a single module in a half-bridge configuration. Each IGBT is paired with an anti-parallel fast recovery free-wheel diode, providing a practical power-switching building block for inverter and motor-control circuits.

Low Collector-Emitter Saturation Voltage

At a collector current of 300A and gate-emitter voltage of 15V, the CM300DY-12NF has a typical collector-emitter saturation voltage of approximately 1.7V at 25°C, helping reduce conduction losses in high-power switching systems.

Electrically Insulated Baseplate

The module features an insulated construction that electrically isolates the internal semiconductor circuitry from the heat-sinking baseplate. The specified isolation withstand voltage between terminals and baseplate is 2500Vrms for one minute.

Designed for Heatsink Installation

The CM300DY-12NF is a chassis-mounted power semiconductor module intended for installation on a suitable heatsink. Proper thermal compound, mounting torque, heatsink selection, airflow, and thermal management are essential for reliable operation at high current.
