FGAF20S65AQ

Overview

The FGAF20S65AQ is a Field Stop Trench IGBT manufactured by onsemi, rated for 650 V collector-emitter voltage and 20 A continuous collector current. It utilizes trench gate technology to achieve low conduction losses and fast switching performance. The device features a soft recovery characteristic in its integrated anti-parallel diode, which minimizes switching losses and electromagnetic interference during operation. Designed for high-efficiency power conversion, it operates within a junction temperature range of -40°C to +175°C and is housed in an insulated package suitable for thermal management.

Feature Summary

• Field Stop Trench IGBT structure for optimized switching and conduction efficiency
• Integrated anti-parallel diode with soft recovery characteristics
• High thermal stability supporting extended operating temperatures

Applications

• High-frequency switch-mode power supplies
• Motor drive inverters
• Induction heating systems

Procurement Notes

Verify the specific datasheet revision and ordering suffixes to ensure compatibility with required packaging and compliance standards. Confirm thermal interface material requirements and mounting torque specifications for the selected package variant before integration into the final assembly process.

Selection Notes

Select this component for designs requiring a balance between low conduction loss and reduced switching noise. Ensure the gate drive circuit provides sufficient voltage swing to fully enhance the trench gate while respecting maximum ratings. Evaluate thermal resistance parameters against the system's heat dissipation capabilities to maintain safe junction temperatures under peak load conditions.

Part Context

This part belongs to onsemi’s field stop trench IGBT portfolio, designed to replace older planar technologies. It offers improved figure-of-merit compared to standard trench devices, making it suitable for applications demanding higher power density and efficiency without compromising reliability or switching speed.

Replacement Considerations

Check pinout compatibility and thermal footprint when substituting with similar 650V/20A IGBTs. Verify that alternative devices meet the same soft-recovery diode specifications to prevent voltage spikes in sensitive circuits.
