Single FETs, MOSFETs Procurement Notes

Verify that the component matches the specific automotive grade designation AUIRFB4610 rather than the commercial IRFB4610 variant. Confirm the manufacturer source is International Rectifier or Infineon Technologies. Ensure the package type is TO-220AB and check for RoHS compliance status as indicated in official documentation before procurement.

Single FETs, MOSFETs Selection Notes

Select this component when automotive reliability standards are required alongside high current handling capabilities. The 100V rating suits low-voltage automotive systems. Consider the 73A current capacity and 190W power dissipation limits relative to your thermal management design. The TO-220AB package facilitates through-hole mounting for robust mechanical connections.

Single FETs, MOSFETs Part Context

This part belongs to the HEXFET family of power MOSFETs produced by International Rectifier, now part of Infineon Technologies. The 'AU' prefix typically denotes automotive-grade variants within this product line, distinguishing them from standard commercial parts like the IRFB4610 while sharing similar core electrical specifications.

Single FETs, MOSFETs Replacement Considerations

The IRFB4610 is a commercial equivalent with identical electrical ratings but lacks automotive qualification. Verify if automotive grade certification is mandatory for your application before substituting.
