ZV933V2TA

Overview

The ZV933V2TA 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 power dissipation of 250 mW at 25°C. Capacitance values range from 42.00 pF to 12.00 pF across reverse voltages of 1 V to 4 V, with a minimum Q of 150 at 4 V and 50 MHz.

Feature Summary

• Octave tuning capability from 0 to 6V
• Low reverse current ensuring excellent phase noise performance
• High Q factor for efficient filtering

Applications

• VCXO and TCXO
• Wireless communications
• Mobile radio

Procurement Notes

Verify the manufacturer origin, as the component was originally developed by Zetex Semiconductors before being acquired by Diodes Incorporated. Confirm the specific ordering suffix (e.g., TA for 7-inch reels) matches the required tape and reel quantity. Ensure the datasheet version aligns with the production batch specifications.

Selection Notes

Select this component when octave tuning and low phase noise are critical requirements. The SOD-523 package offers a compact footprint suitable for space-constrained designs. Evaluate the capacitance tolerance and Q factor against the specific circuit requirements to ensure optimal frequency stability and signal integrity.

Part Context

This part belongs to the ZC930, ZMV930, and ZV931 series of silicon 12V hyperabrupt varactor diodes. The series provides various capacitance options and packaging formats, including SOT-23, SOD-323, and SOD-523, to accommodate different design constraints while maintaining consistent electrical performance profiles.

Replacement Considerations

Direct substitutes within the same series include ZV932V2TA and ZV934ATA, though their capacitance values differ significantly. Cross-manufacturer replacements require careful verification of C-V curves and Q factors to ensure equivalent performance in frequency control circuits.
