CM300DX-24S

Overview

The CM300DX-24S is a dual IGBT module manufactured by Powerex Inc., part of the NX series. It features a center-tapped configuration with two elements, each incorporating a built-in diode and thermistor. The device supports a maximum collector current of 300 A and a collector-emitter voltage of 1200 V. It utilizes a flange mount package with seven terminals and operates at a maximum junction temperature of 150 °C. The module includes an isolated case connection and complies with UL recognition standards.

Feature Summary

• Dual IGBT structure with integrated freewheeling diodes for efficient power switching
• Integrated NTC thermistor for precise thermal monitoring and protection
• Center-tap configuration enabling versatile circuit topologies
• Isolated base plate design for secure mounting and electrical safety

Applications

• Industrial motor drives and inverters
• Uninterruptible power supply (UPS) systems
• High-power welding equipment

Procurement Notes

Verify the specific manufacturer origin, as this component is associated with both Powerex Inc. and Mitsubishi Electric due to historical corporate relationships. Confirm RoHS compliance status and exact pinout compatibility with existing PCB layouts or busbar connections before integration. Ensure the ordering suffix matches the required terminal configuration and packaging specifications.

Selection Notes

Select this module for applications requiring high current handling in a compact dual configuration. The 1200 V rating suits medium-voltage industrial systems. Consider the thermal resistance and cooling requirements associated with the flange mount style. Verify that the gate drive characteristics align with the specified maximum gate-emitter voltage limits to ensure reliable operation.

Part Context

This component belongs to the CM DX series of IGBT modules, designed for general-purpose power conversion. The 'DX' designation typically indicates a dual configuration with anti-parallel diodes. The '24S' suffix denotes specific terminal arrangements and packaging variants within the product line, distinguishing it from other series like the S1 or TX families.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-referencing with similar NX series modules may require detailed electrical parameter matching and mechanical footprint verification.
