Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability variations. Confirm package integrity and marking consistency against official Infineon specifications. Ensure storage conditions meet moisture sensitivity level requirements prior to soldering. Cross-reference ordering information with current product lifecycle status to confirm supply continuity.

Selection Notes

Select this component when a dual varactor with common cathode topology is required for RF tuning. The SOT-323 package suits space-constrained designs. Evaluate the 10 V reverse voltage rating against circuit operating limits. Consider the 5.5 pF baseline capacitance and 3.5 ratio for tuning range requirements. Verify thermal management capabilities for the specified 150°C junction temperature limit.

Part Context

This part belongs to the BBY58 series of varactor diodes from Infineon Technologies. It shares the SOT-323 footprint with variants like BBY5805WH6327XTSA1 but differs in specific electrical parameters and suffix designations. The series targets general-purpose RF tuning needs where moderate capacitance ratios are sufficient.

Replacement Considerations

BBY5805WH6327XTSA1 is a documented variant within the same family sharing the SOT-323 package and common cathode configuration. Verify electrical parameter compatibility before substitution.
