CM300DU-24NFH

Overview

The CM300DU-24NFH is a half-bridge IGBT module manufactured by Powerex Inc. It features a 1200 V collector-emitter breakdown voltage and a continuous collector current of 300 A. The device incorporates an integrated NTC thermistor for thermal monitoring. Designed for chassis mounting, the module operates within a junction temperature range of -40°C to 150°C. It utilizes a flange mount package configuration suitable for high-power industrial applications requiring robust thermal management and electrical isolation.

Feature Summary

• Integrated NTC thermistor for precise internal temperature monitoring
• Half-bridge topology with built-in freewheeling diode
• Chassis mount design for efficient heat dissipation

Applications

• Industrial motor drives
• Uninterruptible power supplies (UPS)
• Induction heating systems

Procurement Notes

Verify the specific suffix 'FH' against official Powerex documentation to confirm pinout and mechanical dimensions. Confirm availability status as distribution channels may list discontinued or obsolete inventory. Ensure the supplier provides original manufacturer packaging and traceability documents to guarantee component authenticity and quality.

Selection Notes

Select this module when a 1200 V rating and 300 A current capacity are required in a half-bridge configuration. The integrated NTC sensor simplifies thermal protection circuitry compared to modules without sensors. Verify that the chassis mounting interface matches the system's cooling plate specifications to ensure proper thermal contact and mechanical stability during operation.

Part Context

This component belongs to the CM series of IGBT modules from Powerex. The 'DU' designation indicates a half-bridge configuration with two elements. The '24' prefix specifies the 1200 V voltage class. The 'NFH' suffix typically denotes specific terminal configurations or thermal characteristics defined by the manufacturer for this particular part number variant.

Replacement Considerations

Direct replacements must match the 1200 V / 300 A half-bridge specification and include an NTC thermistor. Verify mechanical footprint compatibility for chassis mounting. Cross-reference with Powerex's official replacement guide for updated series equivalents if this specific suffix is no longer produced.
