RF Diode Procurement Notes

Verify the specific suffix designation against official Vishay documentation to confirm exact manufacturing revisions and compliance status. Confirm that the procurement channel provides valid traceability for this obsolete part number. Ensure storage conditions align with semiconductor handling standards to prevent degradation prior to assembly.

RF Diode Selection Notes

Select this component when a low-capacitance PIN diode is required for RF frequencies around 100 MHz. The 30V reverse voltage rating suits moderate power levels. Consider the DO-35 package constraints for board space. Verify availability as the product status may be obsolete, necessitating alternative sourcing strategies or design adjustments.

RF Diode Part Context

This part belongs to the BA479 series of RF PIN diodes manufactured by Vishay. The series includes variants like the BA479G and BA479S, sharing similar electrical profiles but potentially differing in packaging or specific manufacturing lot characteristics. These diodes are engineered for consistent performance in microwave and RF signal control applications.

RF Diode Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers should consult Vishay's official obsolescence notices or authorized distributors for potential last-time buy options or approved cross-references.
