Product details

40 V, 195 A, 2 mOhm — the low-voltage high-current switch for 12 V / 24 V rails

The Infineon AUIRFB8407 is an N-channel HEXFET® power MOSFET rated for 40 V drain-source breakdown and 195 A continuous drain current at 25 °C case temperature, housed in a TO-220AB through-hole package.

225 nC gate charge — what it means for the gate-drive budget

A 225 nC total gate charge at 10 V is high by modern trench-FET standards. It means the gate driver must supply enough peak current to charge and discharge the gate capacitance within the desired switching interval.

Active lifecycle, no LTB watch

The AUIRFB8407 carries an Active product status with ROHS3 compliance. There is no last-time-buy or end-of-life notice on record.

Frequently asked questions

AUIRFB8407 vs IRFB8407 — what are the differences?

The AUIRFB8407 is the automotive-qualified variant of the IRFB8407, sharing the same 40 V, 195 A, 2 mOhm ratings and TO-220AB package. The AUIRFB8407 carries additional AEC-Q101 qualification and extended temperature range suitable for under-hood automotive environments, while the IRFB8407 is the industrial-grade version. For non-automotive designs, either may be used; for automotive BOMs, the AUIRFB8407 is the specified part.
