PS21965-ST is a 600V/20A low-loss CSTBTTM inverter bridge for three phase DC-to-AC power conversion. Open emitter type. It is designed for AC100V~200V inverter drive for small power motor control.
The Mitsubishi PS21965-ST is a dual‑in‑line package (DIP) intelligent power module offering a 600 V/20 A low‑loss CSTBT inverter bridge for three‑phase DC‑to‑AC conversion. It integrates drive, protection and system control functions for both upper‑leg and lower‑leg IGBTs, including under‑voltage, short‑circuit and over‑temperature protection.
The manual provides maximum ratings, electrical and thermal characteristics, mechanical data, recommended operation conditions, wiring diagrams, timing charts for protective functions, and guidelines for MCU interface and layout to ensure reliable operation in inverter drive applications.
