Overview
The BBY5302WH6327XTSA1 is a silicon hyperabrupt tuning diode from the BBY53 series, manufactured by Infineon Technologies. It is designed for low tuning voltage operation in VCOs for mobile communications equipment. The component features a single-diode configuration housed in an SCD80 leadless package with white marking. Key electrical characteristics include a maximum reverse voltage of 6 V and a typical capacitance of 5.3 pF at 1 V reverse bias (1 MHz). It exhibits a high capacitance ratio of approximately 2.2 between 1 V and 3 V reverse voltages.
Feature Summary
- High Q hyperabrupt characteristic optimized for low tuning voltage applications
- Designed specifically for Voltage Controlled Oscillators (VCOs) in mobile communications
- Provides a high capacitance ratio at low reverse voltage levels
Applications
- Voltage Controlled Oscillators (VCOs)
- Mobile communications equipment
- Frequency synthesizers
Procurement Notes
Verify the specific suffix 'W' against official documentation to confirm the exact package variant and marking code. Confirm current availability status as automotive-grade components may have lifecycle changes. Ensure the SCD80 package footprint matches the target PCB design constraints before finalizing procurement.
Selection Notes
Select this component when a hyperabrupt tuning profile is required for wide frequency coverage in low-voltage VCO designs. Compare the 6 V reverse voltage rating against the circuit's maximum operating voltage. Evaluate the 5.3 pF nominal capacitance and 2.2 ratio against the required tuning range and linearity specifications for the application.
Part Context
This part belongs to the BBY53 series of silicon tuning diodes. Other variants in the series include BBY53-02L, BBY53-02V, BBY53-03W, and BBY53-05W, which differ in package type (SOT23, TSLP-2-1, SC79, SOD323) and internal configuration (single or common cathode). The BBY5302WH6327XTSA1 specifically utilizes the SCD80 package.
Replacement Considerations
Infineon BBY53-02L, BBY53-02V, BBY53-03W, and BBY53-05W are listed as related parts within the same series. Verify pinout compatibility and package dimensions (SCD80 vs SOT23/SOD323) before substitution.
