Procurement Notes
Verify component authenticity through authorized distributors or official manufacturer channels. Confirm package type matches design requirements, as the series supports multiple surface mount formats. Check datasheet revisions for updated electrical parameters before finalizing integration into production designs.
Selection Notes
Select this component based on required capacitance ratios and operating frequency ranges. Ensure the circuit design accommodates the 12 V reverse voltage limit and thermal constraints defined by the specific package power dissipation ratings. Verify that the hyperabrupt profile aligns with the desired tuning linearity for the target application.
Part Context
This part belongs to the ZC930 series of silicon hyperabrupt varactor diodes. The series includes variants such as ZC930, ZC931, and ZC932, offering different capacitance values while maintaining similar electrical profiles. These devices are designed for miniature surface mount packaging to support compact electronic designs.
Replacement Considerations
Direct substitutes within the same family include ZC930TA, ZC931TA, ZC932TA, and ZC933TA. Selection depends on matching specific capacitance values and Q factors required by the circuit design.
