CM300DU-24H

Overview

The CM300DU-24H is a high-power insulated gate bipolar transistor (IGBT) module manufactured by Powerex Inc. It features a dual configuration with integrated freewheeling diodes, rated for a collector current of 300 Amperes and a collector-emitter voltage of 1200 Volts. The device utilizes a flange mount package design to facilitate efficient thermal management in demanding power electronics applications.

Feature Summary

• Dual IGBT structure with built-in fast recovery freewheeling diodes
• Insulated base plate for electrical isolation and mounting flexibility
• Optimized switching characteristics for high-efficiency power conversion

Applications

• Medium-frequency induction heating systems
• Pulse width modulation (PWM) motor drives
• Uninterruptible power supply (UPS) inverters

Procurement Notes

Verify the specific datasheet revision and manufacturer origin, as Powerex modules are often co-manufactured or rebranded equivalents of Mitsubishi Electric components. Confirm that the physical pinout and thermal interface specifications match your existing heatsink design before finalizing procurement orders.

Selection Notes

Select this component when designing circuits requiring robust 1200V blocking capability with moderate current handling around 300A. Ensure adequate gate drive voltage levels are provided to fully saturate the IGBT and minimize conduction losses during operation.

Part Context

This part belongs to the CM series of insulated IGBT modules, widely utilized in industrial power control. The 'DU' suffix typically denotes a dual unit configuration containing both an IGBT chip and a complementary diode within a single encapsulated package for bridge leg implementation.

Replacement Considerations

Direct functional substitutes include the CM300DU-24NF and CM300DY-24NF. Verify mechanical dimensions and terminal arrangements to ensure compatibility with existing PCB layouts or busbar connections.
