CM75DY-12H

Overview

The Powerex CM75DY-12H is a Dual IGBTMOD™ H-Series module rated for 600V collector-emitter voltage and 75A continuous collector current. It integrates two N-channel IGBTs in a half-bridge configuration, each paired with a discrete super-fast recovery free-wheel diode featuring a reverse recovery time of 110ns. The device operates within a junction temperature range of -40°C to 150°C and supports switching frequencies between 20kHz and 25kHz. Key electrical parameters include a maximum collector-emitter saturation voltage of 2.8V at 75A and a total gate charge of 225nC. Thermal management is facilitated by an isolated baseplate design.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct pinout and terminal configuration. Confirm that the required mounting torque specifications are met during installation to maintain mechanical integrity and thermal performance. Ensure compatibility with standard M5 and M6 fasteners as specified in the outline drawing.

Selection Notes

Select this component for applications requiring a dual IGBT half-bridge configuration with integrated freewheeling diodes. Evaluate the thermal resistance values to determine appropriate heat sinking solutions for the intended operating environment. Consider the peak collector current rating of 150A when designing for transient load conditions or short-circuit protection scenarios.
