PM50CL1B120

Overview

The PM50CL1B120 is a six-pack Intelligent Power Module (IPM) from the L1-series, manufactured by Powerex Inc. It integrates three N-channel IGBTs and their anti-parallel free-wheeling diodes into a single insulated package designed for inverter applications. The module features pin-type main terminals and includes built-in driver circuitry with protection functions such as over-current detection and under-voltage lockout.

Feature Summary

• Integrates three-phase inverter bridge with internal gate drivers
• Includes comprehensive fault protection circuits
• Features pin-type main terminal connections for PCB mounting

Applications

• General purpose AC motor drives
• Servo motor control systems
• Industrial inverter power stages

Procurement Notes

Verify the specific manufacturer origin, as this part number appears in listings for both Mitsubishi Electric Semiconductor and Powerex Inc. Confirm that the component matches the L1-series pin configuration and voltage rating specifications required for your design before procurement.

Selection Notes

Select this module for applications requiring integrated switching and control logic in a compact form factor. Ensure the thermal management system accounts for the junction-to-case thermal resistance values provided in the official datasheet to maintain safe operating temperatures during continuous operation.

Part Context

This component belongs to the IPM L1-series product line, which offers various current ratings and voltage classes. The 'CL' designation indicates a six-pack inverter configuration with pin-type main terminals, distinguishing it from screw-type or seven-pack variants within the same family.

Replacement Considerations

Compatible substitutes include other L1-series modules with matching voltage and current ratings, such as the PM50CL1A120, provided the terminal connection type (pin vs. screw) is compatible with the existing board layout.
