CM50DY-28H

Overview

The CM50DY-28H is a Dual IGBTMOD™ H-Series module from Powerex Inc., rated for 50 Amperes and 1400 Volts. It integrates two N-channel IGBT transistors in a half-bridge configuration, each paired with a reverse-connected super-fast recovery free-wheel diode. Key electrical parameters include a collector-emitter voltage (V_CES) of 1400 V, a continuous collector current (I_C) of 50 A, and a peak collector current (I_CM) of 100 A. The device features an isolated baseplate for simplified thermal management and offers low drive power requirements. Static characteristics specify a typical collector-emitter saturation voltage (V_CE(sat)) of 3.1 V at 50 A and 15 V gate drive.
