Single FETs, MOSFETs Procurement Notes

Verify the specific suffix ZSTRL against official Infineon documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the part number matches the exact manufacturer designation, as International Rectifier assets are managed by Infineon Technologies. Cross-reference datasheets for any revisions that may affect pinout or thermal characteristics before finalizing procurement orders.

Single FETs, MOSFETs Selection Notes

Select this component for applications requiring high current handling in compact surface-mount footprints. The low on-resistance minimizes conduction losses in power paths. Verify that the driving circuit can supply sufficient gate charge to maintain the specified 4 mΩ resistance. Consider thermal management requirements given the 160 A rating and TO-252-3 package constraints.

Single FETs, MOSFETs Part Context

This part belongs to the seventh-generation HEXFET family developed by International Rectifier, now under Infineon. These MOSFETs utilize advanced process techniques to achieve superior efficiency compared to previous generations. The AUI prefix indicates automotive qualification, distinguishing it from standard industrial variants within the same electrical specification family.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes include IRL1404PBF and IRL1404LPBF for through-hole equivalents. Surface-mount replacements may include IRL1404STRR. Verify pin compatibility and thermal resistance values when substituting across different package types such as TO-220 or D2PAK.
