APTGL475U120D4G

Overview

The APTGL475U120D4G is a single-switch IGBT power module utilizing Trench + Field Stop IGBT 4 technology. It features a D4 isolated package with M6 power and M4 signal connectors, designed for direct heatsink mounting. The device supports a collector-emitter breakdown voltage of 1200 V and offers a continuous collector current of 610 A at 25°C case temperature, or 475 A at 80°C. Maximum power dissipation reaches 2082 W at 25°C. The integrated anti-parallel diode provides soft recovery characteristics with a forward voltage of 1.7 V to 2.2 V at 400 A.

Feature Summary

• Soft recovery parallel diodes with low forward voltage (VF)
• Kelvin emitter configuration for simplified gate drive circuitry
• High level of integration with positive temperature coefficient of VCE(sat) for easy paralleling

Applications

• Welding converters
• Switched Mode Power Supplies
• Uninterruptible Power Supplies
• Motor control

Procurement Notes

Verify the specific revision status and manufacturing origin before procurement, as Microchip may issue Product Change Notifications affecting assembly sites or labeling. Confirm that the D4 package dimensions align with your mechanical design constraints. Ensure electrostatic discharge handling procedures are strictly followed during installation, as the components are sensitive to ESD events.

Selection Notes

Select this component when high ruggedness and stable thermal behavior are required in medium-to-high power applications. The positive temperature coefficient of VCE(sat) facilitates reliable parallel operation without complex current balancing circuits. Verify that the operating junction temperature range of -40°C to 175°C meets your environmental specifications and that the 4000 V isolation voltage satisfies safety requirements.

Part Context

This module belongs to the APTGL series of high-speed IGBT4 power modules from Microchip Technology. It is part of a family designed for robust performance in industrial and automotive environments. The D4 package is a standard form factor within this lineup, offering a balance between current capacity and thermal management capabilities for various power conversion topologies.

Replacement Considerations

Direct replacements within the same D4 package and electrical ratings include the APTGL475U120DAG. For higher current density options in similar packages, consider the APTGL60DDA120T3G or APTGL60H120T3G, though pinouts and thermal characteristics must be verified against the datasheet.
