Supervisors Procurement Notes

Verify the specific suffix 'FHX' against the official Fairchild datasheet to confirm tape-and-reel packaging specifications and pinout orientation. Ensure the component matches the exact lot marking requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributors to confirm authenticity and traceability documentation availability prior to procurement.

Supervisors Selection Notes

Select this component when a 75V N-channel MOSFET with low Rds(on) is required in a small footprint. Consider the thermal dissipation capabilities of the SO-8FL package relative to your application's power density. Verify gate charge parameters if high-frequency switching efficiency is critical for your specific circuit topology.

Supervisors Part Context

This part belongs to Fairchild's TrenchMOS family of power transistors, known for optimized performance in power switching applications. The series offers a balance of voltage rating and current handling in surface-mount packages, widely used in consumer electronics and industrial power supplies where space constraints are significant.

Supervisors Replacement Considerations

Check for direct replacements from ON Semiconductor or Littelfuse offering identical 75V N-channel specifications in SO-8FL packages. Ensure pin compatibility and thermal resistance values match before substituting to avoid redesigning the PCB layout or heat sinking infrastructure.
