FMG1G400US60H

Overview

The FMG1G400US60H is a high-power IGBT module manufactured by Fairchild Semiconductor, now part of onsemi. It features a 600V collector-emitter breakdown voltage and supports a continuous collector current of 400A. The module utilizes field-stop IGBT technology to achieve low saturation voltage, enhancing efficiency in high-current applications. Packaged in the 7PM-GA form factor with base mounting, it integrates an anti-parallel diode for half-bridge configurations. The device is designed for robust thermal performance and reliable operation in demanding power conversion environments.

Feature Summary

• High current handling capability with 400A continuous collector current rating
• Low saturation voltage achieved through advanced field-stop IGBT technology
• Integrated anti-parallel diode for efficient half-bridge switching operations
• Robust base-mounted packaging designed for effective thermal management

Applications

• Industrial motor drives and servo systems
• Uninterruptible power supplies (UPS) and inverters
• High-power welding equipment
• Induction heating systems

Procurement Notes

Verify component authenticity through authorized distribution channels due to potential supply chain variations. Confirm specific ordering suffixes match required specifications, as package or electrical variants may exist within the same base model number. Check manufacturer announcements for lifecycle status updates, as this series may have been discontinued or superseded by newer generations from onsemi.

Selection Notes

Select this module for applications requiring high current density and efficient switching at 600V levels. Ensure gate drive circuits are compatible with standard IGBT thresholds. Verify thermal interface material compatibility with the base plate for optimal heat dissipation. Consider parallel operation requirements if higher current capacity is needed beyond the single module's 400A rating.

Part Context

This component belongs to the FMG1G series of IGBT modules, which are widely used in industrial power electronics. The series represents Fairchild's (now onsemi) field-stop technology line, offering improved trade-offs between conduction loss and switching speed compared to earlier planar technologies. The 7PM-GA package is a standard footprint for medium-to-high power modules in this voltage class.

Replacement Considerations

Direct replacements include the FMG2G400US60H from the subsequent generation series. Other compatible options may include equivalent 600V 400A modules from Infineon or Mitsubishi Electric, provided pinouts and thermal characteristics align. Always verify datasheet parameters for saturation voltage and switching times before substituting.
