Single FETs, MOSFETs Procurement Notes

Verify that the specific order includes the 'AU' prefix to ensure automotive qualification compliance. Confirm the package variant matches the required form factor, as the base part number is available in both tube and tape-and-reel configurations. Ensure storage and handling procedures adhere to the specified Moisture Sensitivity Level 1 requirements to maintain device integrity prior to soldering.

Single FETs, MOSFETs Selection Notes

Select this component when automotive reliability and high thermal stability are critical. The 55V rating suits low-voltage automotive systems. Compare the 13.5mΩ RDS(on) against system conduction loss requirements. Consider the 60A silicon-limited current versus the 42A package-limited current based on the PCB thermal design and case temperature conditions to ensure safe operation within the absolute maximum ratings.

Single FETs, MOSFETs Part Context

This part belongs to Infineon's HEXFET family of power MOSFETs, specifically designed for robust performance in demanding environments. The 'AU' designation indicates it meets stringent automotive qualification standards, distinguishing it from standard industrial variants. It represents a balance of low conduction losses and high thermal endurance suitable for modern vehicle electronics.

Single FETs, MOSFETs Replacement Considerations

Direct substitutes must match the 55V rating, N-channel configuration, and D-Pak package. Verify that any replacement also holds AEC-Q101 qualification if automotive use is intended. Check that the replacement's RDS(on) and thermal resistance values meet or exceed the original specifications to avoid derating issues.
