CM300DY-24H

Overview

The CM300DY-24H is a Powerex IGBTMOD™ half-bridge module designed for high-power switching applications. It features a dual N-channel IGBT configuration with integrated super-fast recovery free-wheel diodes. The device supports a collector-emitter breakdown voltage of 1200 V and a maximum continuous collector current of 300 A. Rated for chassis mounting, it operates within a junction temperature range of -40°C to 150°C. The module utilizes an isolated baseplate design to facilitate efficient thermal management and simplified system assembly in industrial environments.

Feature Summary

• Half-bridge configuration integrating two IGBT transistors with reverse-connected super-fast recovery free-wheel diodes
• Isolated baseplate construction providing electrical isolation from the heat sinking surface for simplified thermal management
• Optimized for high-frequency hard switching operations up to 30 kHz and soft switching applications between 60 to 70 kHz

Applications

• High-frequency power supplies
• Induction heating systems
• Industrial welding equipment

Procurement Notes

Verify component authenticity through authorized Powerex distributors or direct manufacturer channels. Confirm specific ordering suffixes against official datasheets as they may indicate variations in terminal plating or packaging. Ensure storage conditions comply with moisture sensitivity levels prior to installation. Request batch-specific test reports if required for critical quality assurance protocols.

Selection Notes

Select this module based on the requirement for a 1200 V rating and 300 A current capacity in a half-bridge topology. Evaluate thermal resistance characteristics against the application's heat sink capabilities to ensure operation remains within the 150°C junction limit. Consider the 30 kHz hard-switching frequency capability when designing gate drive circuits and snubber networks for optimal performance.

Part Context

This component belongs to the IGBTMOD™ series by Powerex Inc., specifically engineered for robust industrial power conversion. The 'DY' designation typically indicates a half-bridge configuration with diodes, while '24H' denotes the 1200 V voltage class and specific package variant. It serves as a core switching element in medium-to-high power electronic converters.

Replacement Considerations

Direct replacements include the CM300DU-24NFH and CM300DU-24H from the same manufacturer family. Verify pinout compatibility and thermal interface dimensions before substitution. Cross-reference with Mitsubishi Electric equivalents if sourcing from alternative semiconductor suppliers.
