ZMV932TC

Overview

The ZMV932TC is a silicon hyperabrupt varactor diode manufactured by Diodes Incorporated, designed for frequency control and filtering applications. It features closely controlled capacitance-voltage (C-V) characteristics and high quality factor (Q). The device operates with a maximum reverse voltage of 12 V and supports octave tuning from 0 to 6 V. Electrical specifications include a typical reverse current of 200 pA and a temperature coefficient of capacitance ranging from 300 to 400 ppm/°C at 3 V and 1 MHz. Power dissipation is rated at 330 mW in the SOD-323 package.

Feature Summary

• Octave tuning capability across a 0 to 6 V range
• Low reverse leakage current ensuring excellent phase noise performance
• High Q factor for efficient frequency control
• Hyperabrupt junction profile for wide tuning ratios

Applications

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

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the correct reel size and tape width configuration. Ensure that the component meets all relevant environmental compliance standards required for the intended deployment environment before finalizing procurement orders.

Selection Notes

Select this component based on its hyperabrupt capacitance-voltage curve which facilitates wide tuning ranges. Evaluate the minimum Q factor requirements at the target operating frequency to ensure signal integrity. Confirm that the power dissipation limits align with the thermal management capabilities of the printed circuit board layout.
