Single FETs, MOSFETs Procurement Notes

Verify the manufacturer designation as International Rectifier or Infineon Technologies on the component marking. Confirm the package type is PG-TO263-3 (D2PAK). Ensure the part meets AEC-Q101 automotive qualification requirements if specified for your application. Check RoHS compliance status based on the specific production batch.

Single FETs, MOSFETs Selection Notes

Select this component when a 60 V N-Channel MOSFET with 43 A current capability is required for automotive environments. The D2PAK package suits applications needing robust thermal performance and surface-mount assembly. Verify that the gate drive characteristics align with the control circuitry used in the target system.

Single FETs, MOSFETs Part Context

International Rectifier was acquired by Infineon Technologies, and its product portfolio, including the HEXFET line, continues under the Infineon brand. The AUIRFS3806 belongs to the automotive-specific series, distinguished by the 'AU' prefix indicating AEC-Q101 qualification. This model represents a standard power switching solution within the broader family of 60 V MOSFETs.

Single FETs, MOSFETs Replacement Considerations

The IRFS3806PBF is a non-automotive equivalent from the same manufacturer. For direct automotive replacements, verify cross-reference lists from Infineon for parts sharing the AU prefix and identical pinout and electrical ratings.
