Overview
The ZV931V2TA 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 reverse leakage current of 100 nA at 8 V. Capacitance values are specified as 13.5 pF (max) at 1 V reverse bias, 7.8 pF (max) at 2.5 V, and 4.0 pF (max) at 4 V. The minimum Q factor is 300 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 with close tolerance C-V characteristics
Applications
- VCXO and TCXO
- Wireless communications
- Mobile radio
Procurement Notes
Verify the manufacturer origin, as the component was originally developed by Zetex Semiconductors before acquisition. Confirm the specific ordering suffix matches the required reel size and tape width specifications. Ensure compliance with RoHS directives and check for any relevant environmental statements prior to procurement.
Selection Notes
Select this component based on its hyperabrupt junction profile suitable for wide tuning ranges. Compare capacitance tolerances and Q factors against circuit requirements. Verify that the SOD-523 package dimensions fit the available PCB space and thermal dissipation limits for the intended operating conditions.
Part Context
This device belongs to the ZC930, ZMV930, and ZV931 series of silicon varactor diodes. The series offers various capacitance options and packaging formats, including SOT-23, SOD-323, and SOD-523. The ZV931V2TA specifically utilizes the SOD-523 footprint with distinct part marking.
Replacement Considerations
Compatible substitutes within the same series include ZC931TA and ZMV931TA, though these utilize different packages (SOT-23 and SOD-323 respectively). Direct pin-to-pin replacement requires verifying package compatibility.
