Overview
The ZMV934TC is a silicon hyperabrupt varactor diode from the ZC930, ZMV930, and ZV931 series manufactured by Diodes Incorporated. It provides closely controlled capacitance-voltage characteristics for frequency control applications. The device features low reverse current leakage, typically 200pA, ensuring excellent phase noise performance. It supports octave tuning from 0 to 6V and offers high Q values. The component is available in miniature surface mount packages including SOT-23, SOD-323, and SOD-523.
Feature Summary
- Close tolerance C-V characteristics
- Low IR (typically 200pA)
- Excellent phase noise performance
- High Q
Applications
- VCXO and TCXO
- Wireless communications
- Pagers
- Mobile radio
Procurement Notes
Verify the specific package variant required, as the base part number covers multiple form factors. Confirm the suffix 'TC' corresponds to the 13-inch reel packaging format with 10,000 units per reel. Ensure compatibility with the intended operating temperature range and power dissipation limits for the selected package type.
Selection Notes
Select based on required capacitance at specific reverse voltages. The ZMV934 variant offers a maximum capacitance of 65 pF at 4V reverse bias. Consider the minimum Q factor of 80 at 50MHz for filtering requirements. Evaluate thermal resistance and power dissipation capabilities relative to the chosen surface mount package.
Part Context
This component belongs to the ZC930, ZMV930, and ZV931 series of silicon 12V hyperabrupt varactor diodes. The series includes variants like ZC930, ZMV930, and ZV931 with different capacitance ranges. The ZMV934 specifically targets applications requiring higher capacitance values compared to lower-numbered series members.
Replacement Considerations
Direct substitutes within the same series include ZC934TA or ZMV934ATA for different packaging options. Cross-reference capacitance and Q specifications when considering alternative manufacturers' varactors to ensure equivalent phase noise and tuning linearity.
