CM300HA-12H

Overview

The CM300HA-12H is a single IGBTMOD™ H-Series power module manufactured by Powerex Inc., rated for 300 Amperes and 600 Volts. It integrates one IGBT transistor with a reverse-connected super-fast recovery free-wheel diode in a flange-mount package. Key electrical parameters include a collector-emitter saturation voltage of 2.1V typical at 300A, a gate threshold voltage range of 4.5V to 7.5V, and a total gate charge of 900nC. The device supports junction temperatures up to 150°C, offers 2500Vrms isolation, and features thermal resistance from junction to case of 0.11°C/W for the IGBT and 0.24°C/W for the diode.

Feature Summary

• Low drive power requirements facilitate efficient control circuitry integration.
• Low collector-emitter saturation voltage minimizes conduction losses during operation.
• Discrete super-fast recovery free-wheel diode ensures rapid switching performance.
• Isolated baseplate design simplifies system assembly and thermal management.

Applications

• AC Motor Control
• Motion/Servo Control
• UPS Systems
• Welding Power Supplies

Procurement Notes

Verify component authenticity through authorized Powerex distributors or direct manufacturer channels. Confirm that the received unit matches the CM300HA-12H designation and packaging specifications. Check for physical damage to the flange mount terminals and ensure proper handling procedures are followed to maintain the integrity of the isolated baseplate and internal semiconductor structures.

Selection Notes

Select this module for high-frequency switching applications operating between 20kHz and 25kHz. Ensure the cooling solution can manage the specified thermal resistance values and that the gate drive circuit provides the required ±15V supply. Verify that the peak collector current capability of 600A aligns with the system's transient load requirements without exceeding junction temperature limits.
