CM50TF-28H

Overview

The CM50TF-28H is a six-IGBT power module from the IGBTMOD™ H-Series by Powerex, Inc. It features a three-phase bridge configuration with discrete super-fast recovery free-wheel diodes. The device supports a collector-emitter voltage (V_CES) of 1400 Volts and a continuous collector current (I_C) of 50 Amperes at Tj = 25 °C. Peak collector current reaches 100 Amperes. Static characteristics include a typical V_CE(sat) of 3.1 Volts at 50A/15V gate drive. Dynamic performance specifies a resistive turn-on delay time of 100 ns and a switching turn-off delay time of 150 ns. Thermal resistance from junction to case is 0.31 °C/W per IGBT and 0.70 °C/W per free-wheel diode.

Procurement Notes

Verify the complete part number against official manufacturer documentation before procurement. Confirm that the specific ordering suffix matches the required electrical ratings and package dimensions. Ensure compatibility with mounting hardware torque specifications, specifically M4 terminal screws at 13 in-lb and M5 mounting screws at 17 in-lb, to maintain mechanical integrity and thermal contact.

Selection Notes

Select this component for applications requiring a six-IGBT three-phase bridge configuration. Evaluate thermal resistance values of 0.31 °C/W for IGBTs and 0.70 °C/W for diodes against system heat sinking capabilities. Verify that the 1400V collector-emitter voltage rating exceeds peak circuit voltages. Consider the 100A peak current capability for transient load conditions while ensuring junction temperature limits are not exceeded during pulse operations.

Part Context

The CM50TF-28H belongs to the IGBTMOD™ H-Series manufactured by Powerex, Inc., located in Youngwood, Pennsylvania. This series is engineered for robust switching applications. The module integrates six transistors into a single isolated unit, replacing multiple discrete components.
