AUIRFS3207Z

Single FETs, MOSFETs Overview

The AUIRFS3207Z is an automotive-grade, single N-channel power MOSFET manufactured by Infineon Technologies using advanced silicon planar trench technology. Designed for high-current applications, it features a maximum drain-source voltage (Vds) of 75 V and a continuous drain current (Id) of 120 A at case temperature. The device exhibits a low on-resistance (Rds(on)) of 3 mΩ at Vgs = 10 V. It supports junction temperatures up to 175°C and is qualified under AEC-Q100 standards. The component is housed in a surface-mount D2PAK package.

Single FETs, MOSFETs Procurement Notes

Verify the specific suffix 'Z' indicates RoHS compliance and halogen-free status as per Infineon documentation. Confirm the package variant matches the required D2PAK footprint. Check for any recent lifecycle notices or obsolescence warnings directly from the manufacturer before finalizing procurement plans.

Single FETs, MOSFETs Selection Notes

Select this component when automotive reliability and high current handling are required. Ensure the application voltage remains below the 75 V limit. Verify that the PCB layout can support the thermal requirements for 120 A operation. Compare Rds(on) specifications against alternative packages if space constraints differ.

Single FETs, MOSFETs Part Context

This part belongs to Infineon's IRFS series of automotive MOSFETs. It shares the same die and electrical characteristics as the non-automotive IRFS3207Z but includes additional qualification testing for automotive environments. It serves as a ruggedized alternative for industrial and consumer electronics requiring higher reliability.

Single FETs, MOSFETs Replacement Considerations

The IRFS3207Z is the non-automotive equivalent with identical electrical performance. For pin-compatible alternatives, verify Rds(on) and Qg values match the design requirements. Ensure any substitute meets AEC-Q100 standards if automotive use is intended.
