AUIRF2807

Single FETs, MOSFETs Overview

The AUIRF2807 is an automotive-grade N-channel HEXFET power MOSFET manufactured by Infineon Technologies, succeeding the International Rectifier IRF2807. It features a maximum drain-source voltage of 75V and a continuous drain current ranging from 75A to 89A depending on the specific package variant. The device exhibits a low on-resistance with a typical value of 9.4mΩ at 10V gate drive. Designed for high reliability, it supports junction temperatures up to 175°C and meets AEC-Q101 standards for automotive applications.

Single FETs, MOSFETs Feature Summary

• Automotive qualification compliant with AEC-Q101 standards for enhanced reliability in vehicle environments.
• Advanced planar technology providing low on-resistance and optimized switching performance below 100kHz.
• Robust thermal capability allowing operation at junction temperatures up to 175°C.

Single FETs, MOSFETs Applications

• Automotive motor control systems
• Electronic braking systems (ABS)
• DC-DC converters and power management circuits

Single FETs, MOSFETs Procurement Notes

Verify that the ordering suffix explicitly indicates the 'AU' prefix to confirm AEC-Q101 automotive qualification. Standard IRF2807 parts lack this certification. Confirm the specific package type matches the thermal requirements of the target application. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability.

Single FETs, MOSFETs Selection Notes

Select the AUIRF2807 when automotive reliability and high temperature tolerance are mandatory. Compare the specific package's current rating against the system's peak load requirements. Verify that the 75V voltage rating provides sufficient headroom for the input supply variations. Consider the thermal resistance characteristics of the chosen package for heat dissipation planning.

Single FETs, MOSFETs Part Context

The AUIRF2807 belongs to the HEXFET family of power MOSFETs originally developed by International Rectifier. Following Infineon's acquisition of IR in 2014, the product line was integrated into Infineon's portfolio. This specific variant represents the automotive-qualified version of the widely used IRF2807 industrial component, maintaining electrical compatibility while adding rigorous quality controls.

Single FETs, MOSFETs Replacement Considerations

The standard IRF2807 serves as the direct non-automotive equivalent. For pin-compatible replacements, verify the specific package variant (TO-220AB, D2PAK, or TO-262) to ensure mechanical fit. Other 75V N-channel MOSFETs may require re-evaluation of avalanche ratings and thermal performance.
