Product details

What this HEXFET does in the circuit

The Infineon AUIRF1405-INF is an automotive-qualified N-channel HEXFET power MOSFET in a TO-220AB through-hole package.

5.3 mOhm Rds(on) — what it means for conduction losses

At 75 A continuous, the I²R loss is under 30 W, which the 330 W package dissipation ceiling handles with a properly heatsinked TO-220. The gate charge of 260 nC at 10 V means the gate driver must deliver a 2.6 µC pulse to switch the device; a standard automotive gate-driver IC with 2 A peak source will turn it on in roughly 130 ns.

Automotive temperature grade and construction

The HEXFET stripe-cell architecture keeps the Rds(on) positive-temperature-coefficient characteristic, which helps parallel operation and prevents thermal runaway at high current. The TO-220AB package is a standard through-hole power package, compatible with existing heatsink clips and PCB layouts for 75 A-class designs.

No last-time-buy or phase-out risk is indicated for this order code.

Frequently asked questions

Is AUIRF1405-INF RoHS compliant?

Yes, the AUIRF1405-INF is ROHS3 compliant, meeting the latest EU RoHS directive requirements.

Can AUIRF1405-INF replace IRF1405?

The AUIRF1405-INF is the automotive-qualified version of the standard IRF1405, sharing the same TO-220AB package and similar 55 V / 75 A ratings. It is a direct drop-in replacement for applications requiring AEC-Q101 qualification, with the same pinout and electrical characteristics.
