Single FETs, MOSFETs Procurement Notes

Verify the specific suffix 'S' indicates the D2PAK package variant when ordering. Confirm AEC-Q100 compliance requirements match your design specifications. Check for RoHS and REACH regulatory status as per current datasheet revisions. Ensure proper ESD handling procedures are followed during assembly due to the sensitivity of MOSFET gates.

Single FETs, MOSFETs Selection Notes

Select this component for designs requiring high current capacity in a compact surface-mount form factor. The 40 V rating suits low-voltage automotive systems. Compare the 5.5 mΩ Rds(on) against alternative packages like TO-220AB if lower resistance is critical. Consider the 120 A current limit relative to your peak load requirements and thermal management capabilities.

Single FETs, MOSFETs Part Context

This part belongs to Infineon's HEXFET family, known for optimized cell technology for low on-resistance. The AUIRF4104S specifically targets automotive markets, offering enhanced ruggedness compared to standard industrial counterparts. It complements other variants in the IRF4104 series by providing a qualified automotive option in the D2PAK package.

Single FETs, MOSFETs Replacement Considerations

The IRFR4104TRPBF serves as a non-automotive equivalent in the DPAK package. For through-hole needs, the AUIRF4104 in TO-220AB offers similar electrical characteristics but with lower on-resistance. Verify pinout compatibility and thermal resistance differences when substituting.
