Product details

55 V, 150 A automotive-grade N-channel MOSFET

The Infineon AUIRF1405ZL-308 is an automotive-qualified N-channel HEXFET power MOSFET rated for 55 V drain-source and 150 A switching current. It is built on the HEXFET trench technology and carries AEC-Q101 qualification, making it suited for under-hood automotive loads such as electric power steering, DC-DC converters, and motor-drive pre-drive stages where junction temperatures can reach 175 °C.

175 °C junction — where it matters

The 175 °C Tj max is the absolute limit for the silicon.

Listed as Active by the manufacturer, so there is no imminent last-time-buy or EOL risk.

Frequently asked questions

Is AUIRF1405ZL-308 AEC-Q101 qualified?

Yes, the AUIRF1405ZL-308 is AEC-Q101 qualified and belongs to the Automotive HEXFET series, making it suitable for automotive-grade applications requiring the AEC-Q101 stress test qualification.

What is the Rds(on) of AUIRF1405ZL-308?

The maximum Rds(on) is 4.9 mOhm at 75 A drain current with 10 V gate-to-source voltage. That is the on-resistance at the rated operating point — conduction loss scales linearly with current squared.

What is the gate charge of AUIRF1405ZL-308?

The total gate charge (Qg) is 180 nC at 10 V gate drive. This figure determines the gate-drive energy per switching cycle and is used to size the gate-driver output stage and estimate switching losses.
