Single FETs, MOSFETs Procurement Notes

Verify the specific suffix (e.g., ZTR) for tape and reel packaging requirements when ordering. Confirm that the component matches the original International Rectifier specifications or current Infineon equivalents if sourcing through third-party distributors. Ensure compliance with RoHS directives and check for radiation hardening if applicable to space-grade variants.

Single FETs, MOSFETs Selection Notes

Select this component for designs requiring high current handling in compact surface-mount packages. The 9mΩ on-resistance minimizes heat generation during continuous operation. Consider the 40V rating for standard 12V or 24V automotive electrical systems. Evaluate thermal management needs based on the 90W power dissipation capability in the TO-252-3 package.

Single FETs, MOSFETs Part Context

This part belongs to the HEXFET power MOSFET series, known for high efficiency and ruggedness. International Rectifier was acquired by Infineon Technologies, which continues production under the same naming conventions. The AUI prefix denotes automotive qualification, distinguishing it from standard industrial counterparts.

Single FETs, MOSFETs Replacement Considerations

Direct replacements include the IRFR3504 for non-automotive use or other HEXFET devices with similar voltage and current ratings. Verify pinout compatibility and thermal resistance values before substituting. Check for updated datasheets from Infineon to ensure parameter consistency.
