CM75DU-12H

Overview

The Powerex CM75DU-12H is a Dual IGBTMOD™ U-Series power module designed for switching applications. It integrates two IGBT transistors in a half-bridge configuration, each paired with a reverse-connected super-fast recovery free-wheel diode. The device features an isolated baseplate to simplify thermal management and system assembly. Key electrical ratings include a collector-emitter voltage (VCES) of 600 Volts and a continuous collector current (IC) of 75 Amperes at Tc = 25°C. Peak collector current reaches 150 Amperes under pulsed conditions. The junction temperature range spans from -40°C to 150°C, with a maximum collector dissipation of 310 Watts. Isolation voltage between main terminals and the baseplate is rated at 2500 Volcs AC for one minute.
