FGI40N60SFTU

Overview

The FGI40N60SFTU is an N-channel Field Stop IGBT manufactured by Fairchild Semiconductor, now part of onsemi. It features a maximum collector-emitter voltage (VCEO) of 600 V and a continuous collector current (Ic) of 40 A at 25°C. The device utilizes field stop technology to achieve low saturation voltage and fast switching characteristics. It is housed in a TO-247 package designed for through-hole mounting. Key electrical parameters include a maximum power dissipation of 349 W, a collector-emitter saturation voltage (VCEsat) of approximately 1.9 V to 2.5 V depending on conditions, and a gate-emitter threshold voltage of 6 V. The component operates within a junction temperature range of -55°C to 150°C.

Feature Summary

• Field Stop IGBT technology for optimized conduction and switching performance
• High input impedance with simple gate drive requirements
• Integrated anti-parallel diode for inductive load applications
• Robust thermal management via TO-247 flange mount package

Applications

• AC and DC motor controls
• General purpose inverters
• Robotics and servo controls
• Switching power supplies

Procurement Notes

Verify the manufacturer lineage as Fairchild Semiconductor was acquired by onsemi; ensure the datasheet corresponds to the correct era or updated specifications. Confirm the suffix 'TU' indicates tape and reel packaging if required for automated assembly, versus tube packaging for manual handling. Check for RoHS compliance status and specific automotive qualification if the application demands AEC-Q101 certification, as standard industrial versions may differ.

Selection Notes

Select this component when a 600V rating is required for medium-power inverter stages. The 40A continuous current rating suits applications where thermal constraints allow for adequate heatsinking. Compare VCEsat and switching times against competitor models like the SGP40N60 series to ensure compatibility with existing gate driver capabilities. Ensure the TO-247 footprint matches the PCB layout and that the thermal resistance values align with the system's cooling design.

Part Context

This device belongs to the Fairchild Ultra-Fast (UF) or Field Stop IGBT family, designed to replace older hard-switching technologies. It serves as a direct successor to earlier N-channel IGBTs in the 600V class, offering improved efficiency in high-frequency switching environments. The transition from Fairchild to onsemi has maintained the core electrical specifications while potentially updating manufacturing processes and packaging standards.

Replacement Considerations

The SGP40N60 is a verified equivalent from the same manufacturer line, sharing similar 600V/40A ratings and TO-247 packaging. Verify pinout compatibility and exact VCEsat values before substitution. Other generic 600V 40A IGBTs in TO-247 packages may require re-evaluation of gate drive voltages and thermal management strategies.
