Overview
The BB171X is a single varactor diode manufactured by NXP USA Inc., designed for surface-mount applications in the SOD-323 package. It features a maximum peak reverse voltage of 30 V and operates within a junction temperature range of -55°C to 125°C. The device exhibits a capacitance of 2.75 pF at 28 V and 1 MHz, with a capacitance ratio of 15.0 under C1/C28 conditions. This component is part of the BB170 basic product family and is currently classified as obsolete.
Feature Summary
- Single-channel varactor configuration for tuning circuits
- Surface-mount construction in compact SOD-323 packaging
- High capacitance ratio for effective frequency modulation
Applications
- RF tuning circuits
- Voltage-controlled oscillators (VCOs)
- Frequency modulation modules
Procurement Notes
Verify availability through authorized distributors as this component is marked obsolete. Confirm RoHS3 compliance and check for any specific handling requirements due to its status. Cross-reference manufacturer documentation for lifecycle updates or recommended alternatives before finalizing procurement plans.
Selection Notes
Select this component for designs requiring a 30 V rated single varactor in an SOD-323 footprint. Ensure the application supports the specified 2.75 pF capacitance at 28 V. Consider the obsolete status when planning long-term production runs and evaluate replacement options early in the design phase.
Part Context
The BB171X belongs to the BB170 series of varactor diodes from NXP. These components are typically used in RF applications where variable capacitance is required for tuning. The 'X' suffix often denotes specific tape-and-reel packaging configurations, though the core electrical characteristics remain consistent with the base BB170 model.
Replacement Considerations
Check for direct substitutes from NXP or other manufacturers offering identical 30 V, SOD-323 varactor specifications. Verify pin compatibility and electrical parameters such as capacitance ratio and reverse voltage ratings before substitution.
