CM400HA-28H

Overview

The CM400HA-28H is a single IGBTMOD™ H-Series power module manufactured by Powerex Inc. It features one IGBT transistor and a reverse-connected super-fast recovery free-wheel diode in a single configuration. The device supports a collector-emitter voltage (VCES) of 1400 Volts and a continuous collector current (IC) of 400 Amperes. Peak collector current reaches 800 Amperes with a junction temperature range of -40°C to 150°C. Electrical characteristics include a typical VCE(sat) of 3.1V at 400A, total gate charge of 2040nC, and diode forward voltage up to 3.8V. Thermal resistance from junction to case is 0.045°C/W for the IGBT and 0.09°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 revisions to validate static and dynamic parameters. Check for any updated safety or isolation ratings relevant to the target application environment.

Selection Notes

Select this module for high-power switching applications requiring 1400V blocking capability and 400A continuous current. Evaluate thermal resistance values to ensure adequate heat sinking for the intended duty cycle. Consider the peak current rating of 800A for transient load conditions. Verify gate drive voltage compatibility with the specified threshold and saturation characteristics. Assess package dimensions for PCB layout and enclosure fitment constraints.

Part Context

This component belongs to the Powerex IGBTMOD™ H-Series, which provides robust power switching solutions. The series includes various current ratings within the same voltage class, allowing for scalable design architectures.
