Microsemi Corp. IGBT Modules APTGL90A120T1G

APTGL90A120T1G is a phase-leg IGBT power module designed for welding converters, switched mode power supplies, uninterruptible power supplies, and motor control applications. It features trench + field stop IGBT4 technology with a 1200 V collector-emitter breakdown voltage and 90 A continuous collector current at 80°C case temperature. The module has a direct-mount, isolated package with low junction-to-case thermal resistance (0.39 °C/W for IGBT, 0.62 °C/W for diode), Kelvin emitter for easy drive, and solderable terminals for PCB mounting. It includes an internal NTC thermistor for temperature monitoring, low stray inductance, and symmetrical design. The device is RoHS compliant, rated for -40°C to 175°C junction temperature, and withstands 4000 V RMS isolation voltage. Reverse bias and short circuit safe operating areas are specified, with integrated soft-recovery diodes and low switching losses.
