Microsemi Corp. IGBT Modules APTGT50A120T1G

APTGT50A120T1G is a single-phase IGBT power module designed for high-frequency switching applications such as welding converters, UPS systems, and motor control. It features Fast Trench + Field Stop IGBT3 technology with a 1200 V collector-emitter breakdown voltage and 50 A continuous collector current at 80°C case temperature. The module has a low junction-to-case thermal resistance of 0.45°C/W for the IGBT and includes an integrated NTC thermistor for temperature monitoring. It supports switching frequencies up to 20 kHz with symmetrical design and very low stray inductance. The package enables direct mounting to a heatsink with 4000 V RMS isolation, RoHS compliance, and solderable terminals for PCB assembly. Thermal and electrical ratings are specified up to a 150°C junction temperature. Optional reverse recovery diodes are soft-recovery with lower forward voltage and reduced switching losses.
