ZV832BV2TA

Overview

The ZV832BV2TA is a silicon hyperabrupt varactor diode from the 830 series, manufactured by Zetex Semiconductors (now Diodes Incorporated). It is designed for frequency control and filtering applications. The device features closely controlled capacitance-voltage characteristics and high Q factors. Key electrical parameters at Tamb = 25°C include a nominal capacitance of 22.0 pF (range 19.8–24.2 pF) measured at VR=2V, f=1MHz. The minimum Q factor is 200 at VR=3V, f=50MHz, with a capacitance ratio (C2/C20) between 5.0 and 6.5 at f=1MHz. The reverse voltage leakage is typically 0.2 nA at VR=20V, and the reverse breakdown voltage is 5V at IR=10µA.

Feature Summary

• Hyperabrupt junction profile providing high tuning ratios for efficient frequency modulation
• Low reverse current leakage ensuring minimal phase noise in oscillator circuits
• High Q factor performance supporting stable operation in RF filtering applications

Applications

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

Procurement Notes

Verify the manufacturer origin, as the datasheet originates from Zetex Semiconductors plc, which was acquired by Diodes Incorporated. Confirm the package type matches the specific suffix requirements for your assembly process. Ensure that the ordering code TA corresponds to 7-inch reels or TC for 13-inch reels if reel size is critical for your manufacturing line. Check for RoHS compliance status relative to current environmental regulations.

Selection Notes

Select this component when a nominal capacitance near 22pF is required with a hyperabrupt tuning curve. Compare against the 832A variant if looser tolerance is acceptable. Consider the SOT23 package dimensions for PCB layout constraints. Evaluate the temperature coefficient of capacitance (300-400 ppm/°C) against your thermal operating environment requirements to ensure frequency stability.

Part Context

This part belongs to the 830 series of silicon hyperabrupt varactor diodes. The series includes single and dual common cathode formats in miniature surface mount packages like SOT23, SOD323, and SOD523. The ZV832BV2TA specifically denotes the B-tolerance version of the 832 model family, offering tighter capacitance specifications compared to the A-version.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source document. Designers should consult the manufacturer's official cross-reference lists or authorized distributor databases for equivalent components within the hyperabrupt varactor category.
