Mitsubishi Electric PM75CSA120 Intelligent Power Module

The Mitsubishi Electric PM75CSA120 is a 75 A, 1200 V three-phase intelligent power module (IPM) that integrates IGBT devices, gate-drive circuitry, and built-in protection in a single insulated baseplate package. It targets high-efficiency power switching and motor control, and is commonly used in industrial inverters, servo drives, UPS systems, and induction heating where compact, reliable power conversion is essential. Key specs include VC ES 1200 V; continuous current 75 A with ~150 A peak; DC bus up to ~900 V (1000 V surge); switching frequency up to ~20 kHz; isolation voltage ~2500 VAC (baseplate isolation); junction temperature range -20 °C to +150 °C; control supply ~15 V typical; weight ~550 g; mounting type baseplate (heatsink mount). It features integrated gate drive and protection logic for short-circuit, overcurrent, overtemperature, and undervoltage. Common replacements include Mitsubishi PM100CSA120, Mitsubishi PM75CVA120, and Infineon FS75R12KT4.
