BB 639 E7906

Overview

The BB639E7906 is a single varactor diode manufactured by Infineon Technologies, designed for UHF and VHF tuner applications. It operates within a reverse voltage range up to 30 V and supports a maximum forward current of 20 mA. The device features a capacitance ratio of 14.7 at a tuning voltage ratio of 1/28V, with capacitance values of 29.75 pF at CT1 and 2.85 pF at CT2. It has a series resistance of 0.65 Ω and is housed in an SOD-323 package. This component is suitable for frequency modulation and tuning circuits requiring stable performance across varying voltages.

Feature Summary

Single configuration optimized for UHF and VHF tuner circuits
High capacitance ratio for effective frequency tuning
Low series resistance for efficient signal transmission
RoHS compliant and lead-free construction

Applications

UHF and VHF tuner circuits
Frequency modulation systems
Radio frequency tuning applications

Procurement Notes

Verify the exact part number suffix, as E7906 may indicate specific tape-and-reel packaging or regional distribution variants. Confirm availability status, as some BB639 variants are marked as not recommended for new designs. Check official Infineon documentation for the most current lifecycle status and ordering information before procurement.

Selection Notes

Select the BB639E7906 when a high capacitance ratio is required for precise frequency tuning in UHF/VHF bands. Ensure the operating voltage does not exceed 30 V reverse bias. Consider the SOD-323 package size for space-constrained PCB layouts. Verify thermal requirements against the specified operating temperature range.

Part Context

The BB639 belongs to Infineon's family of varactor diodes specifically engineered for broadcast and communication tuner applications. It shares functional similarities with the BB659 but offers distinct capacitance characteristics tailored for specific frequency ranges. The E7906 suffix typically denotes a specific packaging or reel configuration within this product line.

Replacement Considerations

Check for direct substitutes like the BB639E7904HTSA1, which shares similar electrical parameters. Verify pin compatibility and capacitance ratios when replacing with other varactor diodes from Infineon or third-party manufacturers.
