PM25RL1A120

Power Driver Modules Overview

The PM25RL1A120 is a Mitsubishi Electric L1-series Intelligent Power Module (IPM) designed for AC400V line applications. It features a 7-pack configuration integrating a three-phase inverter and a brake rectifier. The module utilizes screw-type main terminals and connector-based control interfaces. Key electrical parameters include a 1200V voltage class, a 25A continuous collector current rating, and an isolation voltage of 2500Vrms. Thermal characteristics specify a junction-to-case resistance of 0.97°C/W for the IGBT chip and 1.60°C/W for the free-wheeling diode.

Power Driver Modules Feature Summary

• Integrates a three-phase inverter bridge with a dedicated brake rectifier circuit within a single package.
• Incorporates built-in protection mechanisms including over-current detection and overheating shutdown signals.
• Features gold-plated control input terminals to ensure reliable connection via specialized interface connectors.
• Utilizes ceramic insulated substrates to provide high-voltage isolation between power circuits and the base plate.

Power Driver Modules Applications

• General purpose inverters for AC400V motor drives
• Servo motor control systems
• Industrial pump and fan variable speed drives

Power Driver Modules Procurement Notes

Verify the specific manufacturer origin, as this component belongs to the Mitsubishi Electric L1-series product line. Confirm that the received unit matches the PM25RL1A120 designation and possesses the correct screw-type main terminal configuration. Ensure compatibility with the required HIROSE interface connectors for the control side terminals before integration into the design.

Power Driver Modules Selection Notes

Select this module for AC400V applications requiring a combined inverter and braking function. The 25A current rating suits motors up to approximately 5.5kW. Designers must account for the specific thermal resistance values provided in the datasheet when calculating heat sink requirements. Ensure the control circuit supports the necessary gate drive voltages and timing specifications for safe operation.

Power Driver Modules Part Context

This component is part of the Mitsubishi Electric IPM L1-series lineup, specifically the small-package screw-type variant. It is engineered for robust industrial environments, offering high integration by combining power switching elements with driver and protection logic. The series is widely recognized for simplifying inverter design by reducing external component count and layout complexity.

Power Driver Modules Replacement Considerations

Direct substitutes within the same family include the PM25RL1B120, which shares identical electrical specifications but utilizes pin-type main terminals instead of screw connections. Other L1-series modules with matching voltage and current ratings may serve as functional alternatives if mechanical mounting constraints allow.
