PS21965-4

Overview

The PS21965-4 is a Dual-In-Line Intelligent Power Module manufactured by Mitsubishi Electric Semiconductors and distributed by Powerex. It features a 600V/20A low-loss CSTBT inverter bridge designed for three-phase DC-to-AC power conversion. The module integrates high-voltage power devices with driver circuits to simplify system design and enhance reliability in industrial motor control applications.

Feature Summary

• Integrates low-loss CSTBT technology for efficient power switching
• Combines power bridge and driver circuits in a single dual-in-line package
• Optimized for three-phase DC-to-AC power conversion systems

Applications

• Three-phase AC motor drives
• Industrial servo amplifiers
• Inverter-based power conversion systems

Procurement Notes

Verify the manufacturer origin, as the PS21965-4 is officially produced by Mitsubishi Electric Semiconductors while being listed under Powerex distribution channels. Confirm that the specific suffix '-4' denotes the correct voltage and current rating variant required for your circuit design before procurement.

Selection Notes

Select this module when a compact solution for three-phase inversion is required. The integrated driver simplifies gate drive design compared to discrete components. Ensure thermal management solutions are adequate for the 20A continuous current rating within the dual-in-line form factor constraints.

Part Context

This component belongs to the Intellimod family of intelligent power modules. These modules are engineered to replace complex discrete transistor assemblies, offering reduced board space and improved switching performance through optimized internal layout and integrated protection features.

Replacement Considerations

Compatible substitutes include other variants within the PS21965 series such as the PS21965-4A, PS21965-4C, and PS21965-4S, which share similar electrical characteristics but may differ in package or specific parameter tolerances.
