PS21352-G Ratings, Diagram, Features, and Alternatives Explained
The PS21352-G is a smart power module made by Mitsubishi. It's used to control small motors in things like washing machines, fans, and factory tools. This guide explains its features, ratings, how it works, where to use it, and other models you can choose if this one is not available.
PS21352-G Overview
The PS21352-G from Mitsubishi is a compact, intelligent power module (IPM) designed for three-phase inverter drives in low-power motor control systems. It integrates 600 V, 5 A IGBTs with freewheeling diodes and high-voltage gate drivers, all within a transfer-mold DIP package. With built-in protection features like short-circuit, under-voltage lockout, and fault output signaling, it supports safe and efficient operation.
The module accepts 5 V CMOS/TTL level inputs and is ideal for home appliances and industrial equipment like air conditioners, washing machines, and small servo motors. You may benefit from simplified PCB design thanks to internal drivers and bootstrap support. It runs at PWM frequencies up to 15 kHz and is thermally optimized with a low junction-to-case resistance.
