Procurement Notes
Verify the specific suffix FHT2R against the official datasheet to confirm package type and tape-and-reel specifications. Confirm AEC-Q101 qualification status if automotive compliance is required. Check for end-of-life notifications as availability may be restricted. Ensure the ordering part number matches the exact voltage and current ratings needed for the target application circuit design.
Selection Notes
Select this component when a dual Schottky diode solution is required in a small SOT-543 footprint. The 40 V rating suits low-voltage automotive systems. Consider the 200 mA current limit for load requirements. Verify thermal management needs for the 125 C maximum junction temperature. Compare forward voltage specifications against alternative dual diode packages for efficiency optimization.
Part Context
This component belongs to the RB480Y series of Schottky barrier diodes designed for automotive applications. The series emphasizes high reliability and compact packaging suitable for modern electronic control units. The dual configuration allows for common cathode or independent operation within a single four-terminal surface-mount package.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing PCB footprints and electrical parameters before considering alternative manufacturers.
