Feature Summary

• Dual common-cathode configuration for balanced circuit integration
• High quality factor ensuring low loss at RF frequencies
• Capacitance ratio optimized for wide tuning range performance

Applications

• RF tuning circuits requiring variable capacitance control
• Frequency modulation modules in communication systems
• Voltage-controlled oscillator (VCO) frequency adjustment

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm package integrity upon receipt as the PG-SOT23 form factor requires careful handling. Cross-reference datasheet specifications against current inventory batches to ensure compliance with required electrical tolerances before implementation.

Selection Notes

Select this component when a dual common-cathode varactor is required for symmetric tuning paths. The 18 V rating suits moderate voltage swing applications. Evaluate the 22.7 pF baseline capacitance against circuit impedance requirements. Ensure thermal management supports the 125°C maximum junction temperature limit during operation.

Part Context

This part belongs to the BB814 series of varactor diodes from Infineon Technologies. It utilizes silicon technology housed in a compact SOT-23-3 footprint. The series is designed for general-purpose RF applications where variable capacitance is needed for frequency control or matching networks.

Replacement Considerations

The manufacturer has scheduled this component for obsolescence. Verify if equivalent parts from the same family are available or if alternative manufacturers offer compatible dual common-cathode varactors with similar 18 V ratings and capacitance characteristics.
