PS21962-4

Overview

The PS21962-4 is a Dual-In-Line Intelligent Power Module manufactured by Powerex Inc. It integrates IGBTs and driver circuits for AC motor control applications. The device features a 3-phase configuration with a voltage rating of 600 V and a current capacity of 5 A. It utilizes a 35-PowerDIP package designed for through-hole mounting. The module includes built-in protection functions such as over-current, short-circuit, and under-voltage lockout to ensure reliable operation in industrial environments.

Feature Summary

• Integrates IGBT power switches with dedicated gate drive circuitry within a single hybrid module.
• Provides comprehensive protection mechanisms including over-current detection, short-circuit handling, and under-voltage lockout.
• Designed for direct interface with microcontroller logic signals, simplifying the design of three-phase inverter systems.

Applications

• Three-phase AC motor drives
• Industrial servo amplifiers
• Inverter systems for HVAC equipment

Procurement Notes

Verify the specific suffix (e.g., -4) against official Powerex documentation to confirm pinout compatibility and electrical ratings. Confirm availability status as older IPM series may be discontinued or replaced by newer generations. Ensure thermal management solutions match the module's power dissipation requirements during system integration.

Selection Notes

Select this component when a compact, pre-integrated solution for three-phase motor control is required. Consider the 600V/5A rating relative to the load requirements. Evaluate the 35-PowerDIP package constraints for PCB layout and heat sinking. Verify that the supply voltage range aligns with the system's available power rails.

Part Context

This part belongs to Powerex's Intellimod family of intelligent power modules. These modules combine power semiconductors and control electronics to reduce board space and improve reliability compared to discrete designs. The PS21962-4 represents a specific variant within this lineage tailored for general-purpose AC motor applications.

Replacement Considerations

Consult official Powerex substitution guides for verified equivalents. Cross-reference pinouts and electrical characteristics carefully when considering alternatives from other manufacturers to ensure functional compatibility without redesigning the host circuit.
