AUIRF2804S

Single FETs, MOSFETs Overview

The AUIRF2804S is an automotive-grade N-channel HEXFET power MOSFET in a D2Pak (TO-263) surface-mount package. It features a 40V drain-source breakdown voltage and a maximum on-resistance of 2.0mΩ at VGS=10V. The device supports a continuous drain current of 195A limited by the package, with a pulsed current rating of 1080A. It operates within a junction temperature range of -55°C to +175°C and includes avalanche capability.

Single FETs, MOSFETs Feature Summary

Single FETs, MOSFETs Procurement Notes

Verify the specific suffix 'S' confirms the D2Pak tape-and-reel packaging format. Confirm the component meets the required AEC-Q101 automotive reliability standards for your target application environment. Ensure thermal management designs account for the specified junction-to-case resistance values under steady-state conditions.

Single FETs, MOSFETs Selection Notes

Select this component when a surface-mount solution is required for automotive environments. The D2Pak package provides a balance between thermal performance and PCB space constraints compared to through-hole options. Verify that the 40V rating aligns with the system's maximum operating voltage and transient spikes.

Single FETs, MOSFETs Part Context

This part belongs to the HEXFET family of power MOSFETs from Infineon Technologies. It shares core electrical characteristics with the TO-220 (AUIRF2804) and TO-262 (AUIRF2804L) variants, differing primarily in the physical package form factor and mounting style suitable for surface mount technology assembly lines.

Single FETs, MOSFETs Replacement Considerations

Direct pin-compatible replacements include AUIRF2804L (TO-262) and IRF2804SPBF (D2PAK). Verify that any substitute maintains the same 40V rating, RDS(on) limits, and automotive qualification status before implementation.
