PM50CSD120

Overview

The PM50CSD120 is a three-phase intelligent power module (IPM) manufactured by Powerex Inc. It integrates 1200V current-sense IGBTs with monolithic gate drive and protection logic within an insulated package. The module supports a continuous output current of 50 Amperes at a switching frequency of 15kHz. Key integrated features include detection circuits for over-current, short-circuit, over-temperature, and under-voltage conditions, facilitating reliable operation in motor control applications.

Feature Summary

• Integrates 1200V current-sense IGBTs with monolithic gate drive and protection logic
• Includes dedicated detection and status indication circuits for fault management
• Designed for acoustic noise-less inverter applications

Applications

• General purpose inverters
• Servo drives
• Motor controls

Procurement Notes

Verify the manufacturer designation on the component marking, as the model number PM50CSD120 is also associated with Mitsubishi Electric Semiconductor products. Confirm that the specific unit received matches the Powerex Inc. specifications regarding the Intelligent Power Module architecture and pinout configuration before integration into the design.

Selection Notes

Select this module for applications requiring a compact, three-phase inverter solution with integrated intelligence. The built-in current sensing and protection logic simplify driver circuit design. Ensure the thermal management system can handle the heat dissipation requirements for a 50A continuous current application operating at the specified voltage levels.

Part Context

This component belongs to the family of flat-base type insulated intelligent power modules. These devices are engineered to combine high-power semiconductor chips with control electronics in a single encapsulated unit, reducing assembly complexity and improving reliability compared to discrete component solutions in industrial power conversion systems.
