Variable Capacitance (Varicaps, Varactors) Procurement Notes

Verify the specific ordering suffix 'BTC' against manufacturer documentation to confirm tape and reel specifications. Confirm component availability status as legacy products may be discontinued or subject to last-time-buy notices. Ensure sourcing channels are authorized distributors to guarantee product authenticity and quality compliance.

Variable Capacitance (Varicaps, Varactors) Selection Notes

Select this component when a nominal capacitance near 22pF is required for hyperabrupt tuning curves. Compare the C2/C20 ratio against circuit requirements for desired tuning linearity. Verify that the SOT-23 package dimensions fit the PCB layout constraints and that the thermal dissipation limits are sufficient for the application environment.

Variable Capacitance (Varicaps, Varactors) Part Context

This part belongs to the Zetex 830 series of silicon hyperabrupt varactor diodes, which was acquired by Diodes Incorporated. The series offers various capacitance values and package options, including dual common cathode configurations like the ZMDC832BTA. The ZMV832BTC represents the single-diode variant in the SOT-23 footprint.

Variable Capacitance (Varicaps, Varactors) Replacement Considerations

Direct substitutes within the same series include the ZMV832ATA (7-inch reel) or ZMV832BTA (13-inch reel). Other family members such as ZMV831BTC or ZMV833BTC offer different nominal capacitances but share similar electrical characteristics and packaging.
