PS21965-4 is an integrated power function 600V/20A low-loss CSTBTTM inverter bridge for three-phase DC-to-AC power conversion. It is suitable for AC100V~200V three-phase inverter drive for small power motor control.
This manual describes the Mitsubishi PS21965 dual‑in‑line package intelligent power module, including its transfer‑mold and insulated types. It covers application notes for three‑phase inverter drives, package dimensions, terminal codes, and internal block diagrams.
The document also details protection functions such as short‑circuit and under‑voltage protection, recommended operating conditions, electrical and mechanical ratings, timing charts, and recommended wiring practices for external components and MCU interfaces.
| Inverter supply voltage (Veco) | 450 V |
|---|---|
| Collector‑emitter voltage (VCES) | 600 V |
