Procurement Notes
Verify component authenticity through authorized CEL distributors or certified suppliers. Confirm the specific suffix F3-A matches the required pinout and tape-and-reel specifications. Check manufacturing dates as this part may be obsolete; ensure compatibility with existing assembly processes before procurement.
Selection Notes
Select this component when high-speed digital isolation is required without complex output biasing circuits. The photovoltaic output simplifies design compared to transistor outputs. Ensure the system voltage does not exceed the 7V output limit and that the 25mA input current constraint is respected within the circuit design parameters.
Part Context
This device belongs to the PS8821 series of high-speed photocouplers from CEL. It is part of a family designed for robust signal isolation in noisy environments. The series typically includes variants with different packaging or speed ratings, serving industries requiring reliable galvanic isolation for data integrity.
Replacement Considerations
The PS8802-1 is listed as a similar substitute option. Verify pin compatibility and electrical characteristics against the original datasheet before substitution. Note that the PS8821-1-F3-A is marked as obsolete and no longer manufactured by CEL.
