ZMV832BTA

Variable Capacitance (Varicaps, Varactors) Overview

The ZMV832BTA is a silicon hyperabrupt varactor diode from the 830 series, manufactured by Diodes Incorporated (formerly Zetex). It features closely controlled capacitance-voltage characteristics and high Q factors for frequency control applications. The device operates with a reverse breakdown voltage of 5V and exhibits low leakage current, typically 20nA at 20V. Key electrical parameters include a nominal capacitance of 22pF at 2V/1MHz, a minimum Q of 200 at 3V/50MHz, and a capacitance ratio (C2/C20) ranging from 5.0 to 6.5.

Variable Capacitance (Varicaps, Varactors) Procurement Notes

Verify component authenticity through authorized channels due to potential unauthorized sales risks. Confirm RoHS compliance status as per latest manufacturer statements. Check for obsolete or last-time-buy status before finalizing procurement plans. Ensure proper ESD handling precautions are followed during storage and assembly processes.

Variable Capacitance (Varicaps, Varactors) Selection Notes

Select this component when steep capacitance-voltage slopes are required for wide tuning ranges. Compare against the 12V hyperabrupt range if higher voltage operation is needed. Verify package availability in SOT-23, SOT-323, SOD-523, or SOD-323 formats based on board space constraints. Ensure operating temperature range meets system requirements of -55°C to +150°C.

Variable Capacitance (Varicaps, Varactors) Part Context

This part belongs to the 830 series of silicon hyperabrupt varactor diodes originally developed by Zetex Semiconductors plc. The series includes single and dual common cathode variants designed for precision frequency control. The ZMV832BTA specifically denotes the B-tolerance version packaged in tape and reel format for automated surface mount assembly.

Variable Capacitance (Varicaps, Varactors) Replacement Considerations

Direct substitutes within the same tolerance class include ZMV832ATA. For different packaging, consider ZMV832BTA equivalents in alternative footprints like SOT-23 or SOD-323. Higher voltage alternatives exist in the 12V hyperabrupt range such as ZC930 or ZMV930 if reverse bias requirements exceed 5V.
