Overview
The ZMV934ATC is a silicon hyperabrupt varactor diode from the ZC930, ZMV930, and ZV931 series manufactured by Diodes Incorporated. It features closely controlled capacitance-voltage characteristics and high Q factors for frequency control applications. The device operates with a maximum reverse voltage of 12 V and a forward current rating of 100 mA. At VR=1V, the capacitance ranges from 80 pF to 110 pF; at VR=2.5V, it ranges from 35 pF to 45 pF; and at VR=4V, it ranges from 20 pF to 30 pF. The minimum Q factor at VR=4V and f=50MHz is 80. It utilizes an SOD-323 package.
Feature Summary
- Octave tuning capability from 0 to 6V
- Low reverse leakage current typically 200pA
- Excellent phase noise performance due to low IR
- High Q factor for efficient filtering
Applications
- VCXO and TCXO
- Wireless communications
- Pagers
- Mobile radio
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm packaging details such as reel size or tape width. Confirm RoHS compliance status through the manufacturer's latest datasheet revision. Ensure the component matches the required surface mount package dimensions before integration into the design.
Selection Notes
Select this component based on its hyperabrupt C-V profile suitable for wide tuning ranges. Consider the thermal dissipation limits of the SOD-323 package during operation. Evaluate the temperature coefficient of capacitance for stability requirements in varying environmental conditions.
Part Context
This part belongs to the ZC930, ZMV930, and ZV931 series of silicon 12V hyperabrupt varactor diodes. These devices are designed for miniature surface mount packages including SOT23, SOD323, and SOD523 formats. The series emphasizes low reverse current and high Q for precision frequency control.
Replacement Considerations
Direct substitutes within the same series include ZMV934TA and ZMV934ATA. Verify pinout compatibility and electrical parameters such as capacitance tolerance and breakdown voltage when considering alternative manufacturers.
