VUI9-06N7

Bridge Rectifier Overview

The VUI9-06N7 is a single-phase rectifier module integrating an NPT IGBT and an internally series-connected HiPerFRED free-wheeling diode. It features a 1200 V peak reverse voltage for the input bridge and a 600 V collector-emitter breakdown voltage for the chopper switch. The module supports a continuous collector current of 37 A at 25°C case temperature, with a forward voltage drop of 1.8 V max at 10 A for the diodes. Thermal resistance from junction to case is rated at 0.96 K/W for the IGBT and 1.15 K/W for the freewheeling diode.
