ZV932V2TA

Overview

The ZV932V2TA is a silicon hyperabrupt varactor diode manufactured by Diodes Incorporated, housed in an SOD-523 surface-mount package. It features closely controlled capacitance-voltage characteristics and high Q factors for frequency control applications. Key electrical parameters include a reverse breakdown voltage of 12 V and a maximum forward current of 100 mA. At a reverse voltage of 4 V, the capacitance ranges from 5.5 pF to 10.5 pF with a minimum Q factor of 200 at 50 MHz. The device exhibits low reverse leakage current, typically 100 nA at 8 V, ensuring excellent phase noise performance.

Feature Summary

• Octave tuning capability across a 0 to 6 V range
• Low reverse current ensures very low phase noise performance
• High Q factor for efficient frequency control

Applications

• VCXO and TCXO circuits
• Wireless communications systems
• Mobile radio equipment

Procurement Notes

Verify the manufacturer origin, as the component was originally produced by Zetex Semiconductors before acquisition. Confirm the specific ordering suffix matches the required reel size (7-inch or 13-inch) and tape width. Ensure the part number aligns with the official datasheet specifications to avoid discrepancies in packaging or marking orientation.

Selection Notes

Select this component when octave tuning and low phase noise are critical requirements. The SOD-523 package suits space-constrained designs. Compare capacitance tolerances against circuit sensitivity needs. Verify thermal dissipation limits relative to ambient temperature conditions during operation.

Part Context

This component belongs to the ZC930, ZMV930, and ZV931 series of silicon 12V hyperabrupt varactor diodes. The series offers various capacitance values and package options including SOT-23, SOD-323, and SOD-523. The ZV932V2TA specifically denotes the SOD-523 variant within this family.

Replacement Considerations

Compatible substitutes within the same series include ZV931V2TA and ZV933V2TA. These alternatives share identical package dimensions and pin configurations but offer different nominal capacitance values. Verify that the alternative's C-V curve meets the specific tuning requirements of the design.
