Procurement Notes

This component is officially listed as discontinued or end-of-life by the manufacturer. Verification of current availability requires checking authorized distributors for remaining stock or obsolete inventory. Buyers must confirm lead times and authenticity carefully due to the EOL status. Alternative sourcing strategies should be evaluated immediately to ensure supply chain continuity for existing designs.

Selection Notes

Engineers selecting this part should verify compatibility with the 10 V reverse voltage limit and the specific capacitance characteristics at operating frequencies. The dual common anode structure requires appropriate biasing schemes distinct from common cathode variants. Thermal management considerations are necessary given the high maximum junction temperature rating. Designers should review the official datasheet for detailed electrical curves before finalizing the schematic.

Part Context

The BBY5806WE6327 belongs to the BBY58 series of varactor diodes from Infineon Technologies. This series is characterized by silicon tuning diodes optimized for RF applications. The specific suffix indicates the packaging and tape/reel configuration. It shares functional similarities with other BBY58 variants but differs in internal connection topology and package type.
