MSCGLQ50DH120CTBL2NG

Overview

The MSCGLQ50DH120CTBL2NG is a 1200 V, 50 A asymmetrical bridge high-speed IGBT4 power module. It integrates four IGBTs and four SiC Schottky diodes in an isolated package with screw mounting terminals. Key electrical parameters include a collector-emitter saturation voltage of 1.7 V to 2.4 V at 50 A, a gate threshold voltage of 5.3 V to 6.3 V, and a total gate charge of 230 nC. The module features a junction-to-heatsink thermal resistance of 0.4 °C/W for the IGBTs and operates within a junction temperature range of -55°C to 175°C.
