FMG2G300US60

Overview

The FMG2G300US60 is a molded IGBT power module manufactured by Fairchild Semiconductor, now part of onsemi. It features a half-bridge configuration with an integrated anti-parallel fast and soft recovery freewheeling diode (FWD). The device supports a collector-emitter voltage of 600 V and a continuous collector current of 300 A at a case temperature of 80°C. Key electrical parameters include a saturation voltage of 2.1 V at 300 A and a short-circuit withstand time of 10 µs at 100°C. The module utilizes the 7PM-IA package code and includes an NTC thermistor for thermal monitoring.

Feature Summary

• Short circuit ruggedness rated for 10 microseconds operation under specified conditions
• High-speed switching capability combined with low saturation voltage characteristics
• Integrated fast and soft recovery anti-parallel freewheeling diode
• UL certified component ensuring compliance with safety standards

Applications

• AC and DC motor controls
• General purpose inverters
• Robotics systems
• Servo controls
• Uninterrupted power supplies (UPS)

Procurement Notes

Verify the manufacturer status carefully as Fairchild Semiconductor was acquired by onsemi. Confirm RoHS compliance requirements against specific ordering suffixes, as standard versions may not meet current environmental directives. Check for obsolescence notices or lifecycle announcements from the distributor to ensure long-term availability for production runs.

Selection Notes

Select this module for applications requiring high current handling up to 300 A and robust short-circuit protection. Ensure the cooling system can manage the thermal resistance values provided in the datasheet. Verify that the gate drive circuitry matches the recommended VGE levels and accounts for the total gate charge requirements for optimal switching performance.

Part Context

This component belongs to the FMG2 series of IGBT modules designed for medium-power industrial applications. It represents a transition period product where Fairchild Semiconductor branding appears on documentation prior to full integration into onsemi's portfolio. The 7PM-IA package provides a standardized mounting footprint for easy integration into existing inverter designs.

Replacement Considerations

Direct replacements within the same package and electrical specifications are limited due to the discontinued status. Evaluate newer generations from onsemi such as the FMG2G series variants or comparable offerings from other manufacturers like Infineon or Mitsubishi that match the 600V/300A rating and 7PM-IA form factor.
