PM50RL1B120

Overview

The PM50RL1B120 is a 7-pack Intelligent Power Module (IPM) from the L1-series, designed for three-phase inverter and brake applications. It integrates six IGBTs with free-wheeling diodes for the inverter bridge and one IGBT-diode pair for the braking circuit. The module features a pin-type main terminal configuration and operates at a voltage class of 1200V.

Feature Summary

• Integrates inverter and braking circuits within a single package
• Includes built-in driver circuitry and protection functions
• Utilizes pin-type terminals for direct PCB soldering

Applications

• Three-phase general-purpose inverters
• Servo motor control systems
• Braking chopper circuits

Procurement Notes

Verify that the specific unit matches the L1-series designation and pin-type terminal configuration. Confirm compatibility with the required interface connector specifications for gold-plated control pins. Ensure storage conditions adhere to specified temperature and humidity limits to maintain device integrity prior to installation.

Selection Notes

Select this module based on thermal resistance requirements and power loss calculations for the target operating voltage and current. Consider the specific mounting torque specifications to prevent ceramic isolation damage. Evaluate the need for external snubber circuits or bypass capacitors to manage stray inductance and surge voltages during switching operations.

Part Context

This component belongs to the Mitsubishi Electric IPM L1-series family, distributed by Powerex Inc. It is part of a lineup offering various current ratings and voltage classes for AC200V and AC400V line applications. The series is characterized by its compact design and integrated intelligent drive capabilities.

Replacement Considerations

Compatible substitutes include other L1-series modules such as PM50RL1A120 (screw type) or PM75RL1B120 (higher current). Verify terminal type and pinout compatibility before substitution.
