BBY5702WH6327XTSA1

Overview

The BBY5702WH6327XTSA1 is a silicon tuning diode from the BBY57 series, manufactured by Infineon Technologies. It features a single-diode configuration housed in an SCD-80 surface-mount package. The device operates with a maximum reverse voltage of 10 V and supports junction temperatures up to 125 °C. Key electrical characteristics include a capacitance of 5.5 pF at 4 V (1 MHz) and a capacitance ratio of 4.5 (measured between 1 V and 4 V). It exhibits low series resistance of 0.3 Ω at 470 MHz and is qualified according to AEC-Q101 standards.

Feature Summary

• High Q hyperabrupt tuning characteristic designed for excellent linearity
• Optimized for low tuning voltage operation in voltage-controlled oscillators
• Low series resistance to minimize signal loss in RF circuits

Applications

• Voltage-controlled oscillators (VCOs) in mobile communications equipment
• Temperature-compensated crystal oscillators (TCXOs)
• Voltage-controlled crystal oscillators (VCXOs)

Procurement Notes

Verify component authenticity through authorized channels as this part number may be subject to obsolescence or lifecycle changes. Confirm that the specific ordering suffix matches the required package type and marking specifications. Ensure compliance with RoHS directives and AEC-Q101 qualification requirements relevant to the target application environment before finalizing procurement orders.

Selection Notes

Select this component when a single-ended varactor with high capacitance ratio and low series resistance is required for RF tuning applications. The SCD-80 package suits compact surface-mount designs. Consider the 10 V reverse voltage limit and -55 °C to 125 °C operating temperature range against circuit constraints. Verify compatibility with low-voltage tuning requirements typical in modern mobile communication systems.

Part Context

This component belongs to the BBY57 series of silicon tuning diodes offered by Infineon Technologies. The series includes variants such as BBY57-02L, BBY57-02V, and BBY57-05W, which differ primarily in package type (TSLP-2, SC79, SOT323) and internal inductance. The BBY5702WH6327XTSA1 specifically utilizes the SCD-80 package and carries the H6327XTSA1 suffix indicating tape-and-reel packaging and lead-free construction.

Replacement Considerations

Infineon Technologies lists BBY5702VH6327XTSA1 as a similar alternative. Verify pinout compatibility and electrical parameter equivalence before substitution. Note that different suffixes may indicate variations in package style or manufacturing lot specifications.
