CM400DY-12NF

Overview

The CM400DY-12NF is a power module from the IGBTMOD NF-Series manufactured by Powerex Inc. It features a half-bridge configuration containing two IGBT transistors, each paired with a reverse-connected super-fast recovery free-wheel diode. The device is rated for a collector-emitter voltage of 600 V and a continuous collector current of 400 A at 25°C. Designed for high-power switching applications, it utilizes an isolated baseplate to facilitate thermal management and simplify system assembly.

Feature Summary

• Half-bridge topology integrating two IGBTs with discrete super-fast recovery free-wheel diodes
• Isolated baseplate design enabling simplified heat sinking and system assembly
• Low drive power requirements combined with low saturation voltage characteristics

Applications

• AC motor control systems
• Uninterruptible power supplies (UPS)
• Battery powered supplies

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm datasheet revisions and specific lot markings against official documentation. Ensure proper handling procedures are followed due to semiconductor sensitivity. Cross-reference part numbers carefully as similar designations may exist across different manufacturers.

Selection Notes

Select this module for applications requiring 600 V blocking capability and 400 A current handling in a compact half-bridge format. Evaluate thermal resistance parameters against the intended heatsink solution. Consider the switching frequency limitations imposed by the super-fast recovery diode characteristics when designing the gate drive circuitry.

Part Context

This component belongs to the IGBTMOD NF-Series line of power modules. The series is engineered for robust performance in industrial power conversion environments. The NF-Series designation typically indicates specific internal chip technologies optimized for balancing conduction losses and switching speeds within the 600 V class.

Replacement Considerations

Direct replacements must match the 600 V / 400 A rating and half-bridge pinout. Verify mechanical dimensions and mounting hole patterns to ensure compatibility with existing PCB layouts and heatsinks. Check if alternative suppliers offer equivalent thermal and electrical specifications.
