CM300DY-28H

Overview

The CM300DY-28H is a Dual IGBTMOD™ H-Series power module manufactured by Powerex Inc. It features two IGBT transistors in a half-bridge configuration, each paired with a reverse-connected super-fast recovery free-wheel diode. The device supports a collector-emitter voltage (V_CES) of 1400 Volts and a continuous collector current (I_C) of 300 Amperes at Tj = 25 °C. Peak collector current reaches 600 Amperes. Key electrical parameters include a typical V_CE(sat) of 3.1 Volts at 300A/15V, total gate charge of 1530 nC, and a discrete free-wheel diode reverse recovery time of 300 ns. Thermal resistance from junction to case is 0.06 °C/W for the IGBT and 0.12 °C/W for the FWDi.

Procurement Notes

Verify the complete part number against official manufacturer documentation before procurement. Confirm that the ordering suffix matches the required voltage and current ratings. Ensure compatibility with mounting hardware specifications, specifically M6 terminal and mounting screws with a maximum torque of 26 in-lb. Cross-reference datasheet revision dates to ensure accurate electrical characteristics are applied.

Selection Notes

Select this component for applications requiring a dual IGBT half-bridge topology with high voltage blocking capability. Evaluate thermal management requirements based on the specified junction-to-case thermal resistances. Ensure gate drive circuits can supply the necessary total gate charge of 1530 nC. Verify that peak load currents do not exceed the 600 Ampere limit without violating junction temperature constraints.

Part Context

This module belongs to the H-Series lineup of Dual IGBTMOD™ components. It is designed for switching applications where compact packaging and efficient heat sinking are critical. The isolated baseplate separates electrical components from the thermal interface, allowing direct mounting to heatsinks without additional insulators.

Replacement Considerations

Direct replacements must match the 1400V/300A rating and half-bridge configuration. Verify pinout compatibility and mechanical dimensions, particularly the M6 mounting thread pattern and overall footprint. Check dynamic characteristics like switching times and reverse recovery charge to ensure circuit stability is maintained.
