Product details

80 V N-channel power MOSFET with AEC-Q101 qualification

The Infineon IAUZ40N08S5N100ATMA1 is an N-channel enhancement-mode power MOSFET from the OptiMOS™-5 series, built on a metal-oxide semiconductor technology. The junction temperature range is -55°C to 175°C, with AEC-Q101 qualification.

The 10 mOhm Rds(on) maximum at 20 A and 10 V is the conduction-loss floor for this part. Paired with a maximum gate charge of 24.2 nC at 10 V, the figure of merit (Rds(on) × Qg) is moderate — the part is optimised for hard-switched topologies like DC-DC converters and motor-drive bridges where conduction losses dominate at lower switching frequencies. Input capacitance Ciss is 1591 pF typical at 40 V Vds, which sets the switching energy per cycle. The drive voltage range specified for Rds(on) is 6 V to 10 V, allowing compatibility with both 5 V logic-level gate drivers and standard 10 V gate drives.

Frequently asked questions

Is IAUZ40N08S5N100ATMA1 AEC-Q101 qualified?

Yes, the IAUZ40N08S5N100ATMA1 carries AEC-Q101 qualification, the automotive-grade discrete semiconductor standard. This means the part has passed the required reliability stress tests (HTRB, H3TRB, TC, etc.) and is supported by PPAP documentation suitable for submission to OEM auditors.
