ZC934ATA

Overview

The ZC934ATA is a silicon hyperabrupt varactor diode from the 830 series, manufactured by Diodes Incorporated. It provides a capacitance of 95 pF at 1V reverse voltage and 25 pF at 4V reverse voltage, with a minimum Q factor of 80 at 4V and 50MHz. The device supports octave tuning from 0 to 6V and features low reverse current leakage of typically 200pA. It operates within a temperature range of -55°C to +150°C and is housed in an SOD-323 surface-mount package.

Feature Summary

Octave tuning capability across a 0 to 6V voltage range
Low reverse current leakage for excellent phase noise performance
High quality factor (Q) characteristics
Close tolerance capacitance-voltage (C-V) characteristics

Applications

Voltage-Controlled Crystal Oscillators (VCXO)
Temperature-Compensated Crystal Oscillators (TCXO)
Wireless communications systems
Mobile radio equipment

Procurement Notes

Verify the manufacturer part number against official datasheets before procurement. Confirm that the ordering suffix matches the required tape and reel specifications. Ensure compliance with RoHS directives and check for any product change notifications or obsolescence notices prior to finalizing orders.

Selection Notes

Select this component when high Q factors and low phase noise are critical for frequency control applications. The hyperabrupt junction profile enables wide tuning ranges suitable for VCXO and TCXO designs. Verify that the operating voltage and temperature requirements align with the specified absolute maximum ratings.

Part Context

This component belongs to the 830 series of silicon varactor diodes originally developed by Zetex Semiconductors plc and is now distributed by Diodes Incorporated. The series includes various capacitance options packaged in miniature surface-mount formats such as SOT-23, SOD-323, and SOD-523.
