CM800DU-12H

Overview

The Powerex CM800DU-12H is a Dual IGBTMOD U-Series power module rated at 600V collector-emitter voltage and 800A continuous collector current. It integrates two IGBT transistors in a half-bridge configuration, each paired with a reverse-connected super-fast recovery free-wheel diode. The device features an isolated baseplate for simplified thermal management and system assembly. Key electrical characteristics include a typical VCE(sat) of 2.55V at 25°C and 800A, a peak collector current of 1600A, and a junction temperature range of -40°C to 150°C. Thermal resistance from junction to case is 0.083°C/W for the IGBT and 0.13°C/W for the diode.

Procurement Notes

Verify the specific part number CM800DU-12H against manufacturer documentation to confirm compatibility with your thermal and electrical requirements. Ensure that mounting torque specifications are strictly followed during installation to maintain isolation integrity and prevent mechanical failure. Cross-reference datasheet parameters such as VCES and IC ratings with your system's operational limits before procurement.

Selection Notes

Select this module for applications requiring high current handling up to 800A with a 600V blocking capability. Consider the thermal resistance values when designing the heatsink interface, ensuring proper application of thermal grease to achieve the specified contact thermal resistance. Verify that the gate drive circuitry can supply the necessary total gate charge without exceeding the maximum gate-emitter voltage rating of ±20V.

Part Context

This component belongs to the Powerex Dual IGBTMOD U-Series, designed specifically for robust switching applications. The series utilizes advanced packaging to provide electrical isolation between the main terminals and the heat-sinking baseplate. This architecture supports high-power density designs commonly found in industrial motor drives and power conversion equipment where reliability under heavy load conditions is critical.

Replacement Considerations

When evaluating substitutes, ensure the replacement module matches the 600V/800A rating and maintains similar physical dimensions for board compatibility. Verify that the alternative device offers comparable switching speeds and thermal resistance characteristics to avoid derating the system or modifying the existing cooling infrastructure.
