Product details

What this part is and where it fits

The Infineon AUIRFU8403-701TRL is an N-channel Automotive HEXFET power MOSFET rated for 40 V drain-source and 100 A continuous drain current. It carries AEC-Q101 qualification and a 175°C maximum junction temperature, placing it in the under-hood and chassis-domain tier of automotive power switching. The 3.1 mOhm max on-resistance at 76 A and 10 V gate drive keeps conduction losses low enough for motor-drive, solenoid, and DC-DC converter outputs where board space and heatsinking are tight.

Gate drive and switching

Gate-source voltage is rated to ±20 V. Total gate charge is 99 nC at 10 V. Input capacitance is 0.0032 µF.

Thermal and package

The 99 W power dissipation rating and 175°C Tj maximum are specified. Through-hole mounting provides thermal transfer to a heatsink.

Lifecycle and sourcing

The AUIRFU8403-701TRL is listed as Active with no end-of-life notice.

Frequently asked questions
