Overview
The BB135,135 is a single varactor diode manufactured by NXP Semiconductors. It operates within a temperature range of -55°C to +125°C and utilizes an SMD/SMT mounting style in the UMD-2 package. Key electrical specifications include a reverse voltage (Vr) of 30 V and a capacitance of 17.5 pF. The device achieves a minimum tuning ratio of 8.9 under test conditions of 0.5 V and 28 V. This component belongs to the BB135 series and is classified under Diodes & Rectifiers.
Feature Summary
- Designed for surface-mount assembly using the compact UMD-2 package format.
- Provides high thermal stability with an extended operating temperature range up to +125°C.
- Offers specific capacitance characteristics suitable for RF tuning applications.
Applications
- RF circuit tuning
- Voltage-controlled oscillator design
- Frequency modulation circuits
Procurement Notes
Verify current availability status as the product lifecycle is listed as obsolete or restricted. Confirm RoHS compliance details through official documentation before integration. Ensure the ordering suffix matches the required tape and reel packaging configuration for automated assembly processes.
Selection Notes
Select this component when a 30 V reverse voltage rating and 17.5 pF capacitance are required. The UMD-2 package is suitable for space-constrained PCB layouts. Verify that the minimum tuning ratio of 8.9 meets the specific frequency range requirements of the target application design.
Part Context
This part is a member of the BB135 series from NXP Semiconductors. It shares the core varactor functionality with other devices in the family but differs in specific electrical parameters such as capacitance and tuning ratio. The BB135,135 variant specifically denotes the tape and reel packaging configuration.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided data. Consider evaluating other varactor diodes from the same manufacturer with similar Vr and capacitance ratings if direct replacement is necessary.
