Applications

• Frequency modulation (FM) circuits
• Voltage-controlled oscillators (VCOs)
• RF tuning networks

Procurement Notes

Verify component authenticity through official Infineon channels or authorized distributors. Confirm the part status as obsolete and assess availability from secondary market suppliers like Rochester Electronics if immediate procurement is required. Ensure packaging integrity matches reel specifications.

Selection Notes

Select this component for designs requiring a dual varactor in a compact SOT-23 footprint. Verify that the 18 V reverse voltage rating meets the circuit's peak requirements. Consider the 47.5 pF baseline capacitance and 1.71 tuning ratio for oscillator design calculations. Note the obsolete status when planning long-term production runs.

Part Context

This part belongs to the BB804 series of dual varactor diodes from Infineon. It shares the core BB804 functionality but includes specific ordering suffixes indicating the PG-SOT23 package and tape-and-reel shipping format. It serves as a specialized variant within the broader family of tuning diodes offered by the manufacturer.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, alternative sourcing may require checking secondary distributors or evaluating generic equivalents with matching electrical parameters.
