Procurement Notes
Verify component authenticity due to end-of-life status. Confirm RoHS compliance details via official datasheet. Check for alternative sourcing channels as manufacturer discontinuation may affect long-term availability. Validate package type matches design requirements before integration.
Selection Notes
Select this component for low-power analog applications requiring high input impedance. Ensure circuit voltage does not exceed the 50 V breakdown limit. Consider thermal management within the 100 mW dissipation constraint. Verify compatibility with existing TO-92-3 footprints in the design.
Part Context
This part belongs to the KSK30 series of N-channel JFETs from onsemi. It shares family characteristics with other devices in the lineup but is distinct in its specific voltage and current ratings. The TO-92-3 form factor aligns with common discrete transistor standards used in consumer and industrial electronics.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, direct pin-to-pin replacements should be verified against updated manufacturer catalogs or equivalent generic JFET specifications.
