Procurement Notes
This component is identified as discontinued or end-of-life. Availability is restricted, and it may not be sold in all regions through standard distributors. Verification of current stock status and alternative sourcing channels is required before procurement planning. Compliance with RoHS directives should be confirmed via official documentation.
Selection Notes
Designers should consider the single-diode configuration and SOT-23-3 footprint when integrating this part. The 25 V reverse voltage limit and 200 mA forward current define the operational boundaries. Thermal management must account for the -55°C to +150°C junction temperature range. Since the part is discontinued, evaluating equivalent active components with similar capacitance and voltage ratings is necessary for new designs.
Part Context
The ZC832ATA belongs to the varactor diode category from Diodes Incorporated. It is functionally related to other parts in the 830 series, such as the ZC831ATA, which shares similar packaging but differs in specific capacitance values. These components are classified under discrete semiconductor diodes and rectifiers.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source data. Designers should consult manufacturer databases for active equivalents with matching SOT-23-3 packages and comparable varactor characteristics.
