PS21661-RZ

Overview

The PS21661-RZ is a Single-In-Line Intelligent Power Module (SIP-IPM) manufactured by Powerex, rated for 3 Amperes and 600 Volts. It integrates fifth-generation IGBTs, free-wheeling diodes, application-specific high-voltage integrated circuits (HVICs), and protection circuitry within an ultra-compact transfer-mold package. The module operates with a single power supply and features direct CPU connection capabilities. Key electrical parameters include a collector-emitter voltage of 600V, a continuous collector current of 3A, and a peak collector current of 6A. Control supply voltages are specified between 13.5V and 16.5V.

Procurement Notes

Verify the specific suffix against official documentation to confirm pinout and packaging variations. Ensure the design accommodates the required heatsink operation temperature limits and mounting torque specifications. Confirm that external component selection aligns with the recommended conditions for use, particularly regarding bootstrap supplies and current sensing resistors.

Selection Notes

Select this module for applications requiring a compact solution for driving small three-phase motors. Consider the thermal resistance characteristics and the requirement for a heatsink operation temperature up to 100°C. Evaluate the need for direct CPU interfacing and the benefits of integrated fault output signals when designing the control logic.

Part Context

This component belongs to the Intellimod family of intelligent power modules from Powerex. These modules are designed to reduce inverter size and overall design time by combining power devices and control electronics. The SIP-IPM format distinguishes it from dual-in-line or larger modular packages, offering a specialized form factor for space-constrained motor drive applications.
