Single FETs, MOSFETs Procurement Notes

Verify the specific suffix of the part number, as variations may indicate different tape-and-reel lengths or packaging configurations. Confirm that the component is sourced from authorized distributors to ensure authenticity. Check the lifecycle status, as this model may be subject to obsolescence notices. Ensure the supplier provides valid RoHS compliance documentation. Validate the datasheet version matches the manufacturing batch requirements.

Single FETs, MOSFETs Selection Notes

Select this component when a 250 V rating is required for automotive switching applications. Consider the 275 mΩ on-resistance for efficiency calculations at 9.3 A load currents. Evaluate the DPAK-3 package for PCB space constraints and thermal performance needs. Verify compatibility with logic-level drivers due to the 13 nC gate charge specification. Compare against alternative MOSFETs if higher current capacity or lower resistance is necessary.

Single FETs, MOSFETs Part Context

This component belongs to the IRFR series of Power MOSFETs produced by Infineon Technologies. The 'AU' prefix denotes automotive qualification, distinguishing it from standard industrial variants. It utilizes advanced HEXFET process technology to achieve low on-resistance per silicon area. The product line is designed for robust performance in high-temperature automotive environments.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes must match the 250 V rating, N-channel configuration, and DPAK-3 package. Verify equivalent on-resistance and gate charge specifications to maintain circuit performance. Check for identical AEC-Q100 qualification if automotive reliability is mandatory. Consult official replacement lists from Infineon for validated cross-reference parts.
