The AU series of automotive-qualified MOSFETs are available in a variety of SMD and through-hole packages. One device in the series, the AUIRL1404S logic-level-gate-drive MOSFET, operates at 40V, and other devices in the series use standard-gate drives and operate at 40,55, and 75V. The MOSFETs undergo dynamic- and static-part average testing and 100%-automated wafer-level visual inspection as part of the vendor's quality initiative targeting no defects. The vendor's BOM for the AU demonstrates a maximum on-resistance shift of less than 10% after 1000 temperature cycles of testing, exceeding AEC-Q101's qualification requiring no more than 20% change. Prices begin at 42 cents and $1.22 (100,000) for the standard-gate-drive AUIRFZ44N and logic-level-gate-drive AUIRL1404S, respectively.
