CM400DU-24F

Overview

The CM400DU-24F is a dual IGBT module from the Powerex NFH-Series, rated for 400 Amperes and 1200 Volts. It integrates two N-channel Insulated Gate Bipolar Transistors in a half-bridge configuration, each paired with a reverse-connected super-fast recovery free-wheel diode. The components are isolated from the heat-sinking baseplate to facilitate thermal management. Designed for high-frequency operation, it supports 30 kHz for hard switching and 60 to 70 kHz for soft switching applications.

Feature Summary

• Half-bridge configuration with integrated super-fast recovery free-wheel diodes
• Isolated baseplate design for simplified system assembly and thermal management
• Optimized for high-frequency switching up to 70 kHz

Applications

• Power Supplies
• Induction Heating
• Welders

Procurement Notes

Verify the specific suffix 'F' against official Powerex documentation to confirm exact electrical characteristics and pinout compatibility. Ensure the component meets required RoHS or lead-free standards if mandated by the target application environment. Cross-reference datasheet revisions to validate performance parameters before integration.

Selection Notes

Select this module for applications requiring robust high-frequency switching capabilities in both hard and soft switching topologies. The isolated baseplate simplifies mounting and thermal interface design. Verify that the 400A current rating and 1200V voltage withstand capability align with the system's peak operational demands and safety margins.

Part Context

This component belongs to the CM400DU series of dual IGBT modules manufactured by Powerex. It shares the same core specifications as variants like the CM400DU-24NFH, differing primarily in manufacturing suffixes which may indicate specific testing or packaging variations within the NFH-Series product line.

Replacement Considerations

The CM400DU-24NFH is a confirmed substitute part number with identical 400A/1200V ratings and functional description.
