CM1400DU-24NF

Overview

The CM1400DU-24NF is a Mega Power Dual IGBT module manufactured by Powerex. It features a half-bridge configuration with two N-channel insulated gate bipolar transistors, each paired with a discrete super-fast recovery free-wheel diode. The device supports a maximum collector current of 1400 A and a collector-emitter breakdown voltage of 1200 V. It utilizes an isolated baseplate design for simplified thermal management and system assembly. The module operates at a maximum junction temperature of 150 °C and is housed in a flange-mount package.

Feature Summary

• Half-bridge configuration integrating two IGBTs with reverse-connected super-fast recovery free-wheel diodes
• Isolated baseplate construction to facilitate direct heat sinking and simplify system assembly
• Low drive power requirements combined with low saturation voltage characteristics

Applications

• High power uninterruptible power supply systems
• Large motor drive applications
• Utility interface inverters

Procurement Notes

Verify the manufacturer source carefully as this component is also produced by Mitsubishi Electric under identical specifications. Confirm that the specific datasheet corresponds to the Powerex version when sourcing. Ensure the ordering suffix matches the required electrical parameters exactly. Request official documentation to validate the isolation and thermal characteristics before integration into critical power systems.

Selection Notes

Select this module for high-current switching applications requiring robust thermal isolation. The 1400 A rating suits heavy-duty industrial loads. Verify that the gate drive circuitry aligns with the low drive power specification. Ensure the cooling infrastructure can handle the thermal dissipation associated with the 1200 V blocking capability and high current density in the half-bridge topology.

Part Context

This component belongs to the Mega Power Dual series designed for high-power switching use. It represents a high-current variant within the dual IGBT family, offering superior current handling compared to lower-amperage models. The module integrates both the switching element and the freewheeling diode into a single compact unit to reduce parasitic inductance and improve switching performance in demanding environments.

Replacement Considerations

The Mitsubishi Electric CM1400DU-24NF is a confirmed equivalent part number with identical electrical ratings and pinout configuration. Verify mechanical mounting dimensions and thermal interface specifications to ensure compatibility during substitution.
