Mitsubishi Electric PM150DSA120 Intelligent Power Module

The Mitsubishi Electric PM150DSA120 Intelligent Power Module is an integrated IGBT module with built-in gate drive and protection circuitry, designed for high-efficiency switching in industrial automation and power electronics applications. It combines IGBT devices with a freewheel diode and control circuitry in a flat-base insulated package and is commonly used in inverters, servo drives, UPS systems, and motor-control equipment for power conversion and drive repair. Key specifications include a 1200 V VCES rating, 150 A continuous current (≈300 A peak), switching frequency up to ~20 kHz, and a DC bus supply around 800–900 V; it provides 2500 Vrms isolation and includes overcurrent, short-circuit, overtemperature, and undervoltage protections, with an operating temperature range of -20°C to 100°C and a weight near 430 g. This is a discontinued / legacy module; common replacements are Mitsubishi PM150CSA120, PM150RLA120, and PM200DSA120.
