Procurement Notes
Verify the exact ordering suffix against official Infineon documentation, as variations such as HTSA1 or XTSA1 may exist. Confirm component status, as this part number may be listed as obsolete or end-of-life. Ensure RoHS compliance matches current regulatory requirements before procurement.
Selection Notes
Select based on required capacitance tuning range and Q factor at specific operating frequencies. Verify that the 18 V reverse voltage rating exceeds the maximum expected bias voltage. Ensure the PG-SOT23 package footprint aligns with the PCB layout constraints.
Part Context
This component belongs to the BB814 family of dual varactor diodes designed primarily for FM radio frequency applications. The base model BB814 defines the core electrical characteristics, while the suffix indicates specific packaging and tape-and-reel configurations provided by Infineon.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided source material. Consult Infineon's official replacement guide or distributor cross-reference lists for verified alternatives if this component is discontinued.
