CM400HA-12H

Overview

The CM400HA-12H is a single IGBTMOD™ H-Series power module manufactured by Powerex Inc. It integrates one IGBT transistor and a reverse-connected super-fast recovery free-wheel diode within an isolated baseplate package. The device supports a collector-emitter voltage of 600 Volts and a continuous collector current rating of 400 Amperes at 25°C. Peak collector current reaches 800 Amperes, with a maximum junction temperature of 150°C. Static characteristics include a typical VCE(sat) of 2.1 Volts at 400A/15V and a total gate charge of 1200 nC. Thermal resistance from junction to case is 0.085°C/W for the IGBT and 0.18°C/W for the diode.

Procurement Notes

Verify the complete part number against official manufacturer documentation before procurement. Confirm that the specific ordering suffix matches the required electrical and mechanical specifications. Ensure compatibility with mounting hardware torque limits and thermal interface materials. Cross-reference datasheet revision dates to validate parameter accuracy. Request component traceability certificates if required for critical industrial or medical applications.

Selection Notes

Select this module for applications requiring high current handling in a compact footprint. Evaluate thermal resistance values against the expected heat sink capacity to maintain junction temperatures below 150°C. Consider the 70ns diode recovery time when designing snubber circuits or selecting gate resistors for the target switching frequency range. Verify that the drive circuit can supply the necessary gate charge without excessive delay.

Part Context

This component belongs to the Powerex IGBTMOD™ H-Series line, designed specifically for robust switching applications. The series utilizes an isolated baseplate architecture to separate high-voltage components from the thermal management surface. This configuration simplifies mechanical integration while maintaining electrical safety isolation ratings suitable for industrial power conversion systems.

Replacement Considerations

Consult official cross-reference lists for mechanically compatible alternatives. Verify pinout alignment and terminal dimensions before substitution. Ensure replacement devices meet or exceed the original 600V blocking voltage and 400A current ratings. Check thermal impedance curves to confirm equivalent cooling performance.
