QJD1210011

Overview

The Powerex QJD1210011 is a split dual Silicon Carbide (SiC) MOSFET module rated for 1200V drain-source voltage and 100A continuous drain current. It integrates two individual N-channel SiC transistors, each paired with a reverse-connected fast recovery free-wheeling Schottky diode. The device features an isolated baseplate constructed from AlSiC material with Aluminum Nitride isolation to ensure electrical safety and simplified thermal management. Key electrical parameters include a maximum junction temperature of 175°C, a typical on-resistance of 15mΩ at 25°C, and a gate threshold voltage ranging from 1.5V to 5.0V. The module utilizes a screw-mount installation style with dimensions of approximately 109.8mm x 56.1mm x 18.0mm.
