Procurement Notes
Verify end-of-life status prior to procurement as discontinuation notifications have been issued. Confirm that the SOD-323 package and electrical parameters align with existing design requirements. Ensure compliance with RoHS specifications. Review official datasheets for final technical validation before integration into production systems.
Selection Notes
Select this component for designs prioritizing low tuning voltage efficiency in VCO architectures. The hyperabrupt junction profile offers specific capacitance-voltage characteristics suitable for precise frequency control. Consider the SOD-323 footprint for space-constrained PCB layouts requiring reliable surface-mount assembly.
Part Context
This part belongs to the SMV1247–SMV1255 series of silicon hyperabrupt junction varactor diodes. These components are engineered specifically for RF applications demanding efficient voltage-controlled tuning. The series provides standardized performance metrics for designers integrating variable capacitance elements into high-frequency signal generation circuits.
Replacement Considerations
Check for direct substitutes within the SMV1247–SMV1255 series. Verify package compatibility and electrical parameter equivalence for any alternative varactor diodes.
