BB68902VH7902XTSA1

Overview

The BB68902VH7902XTSA1 is a silicon tuning diode from the BB689 series, manufactured by Infineon Technologies. It is designed for VHF TV tuners and housed in an SC79 surface-mount package. The device features a single diode configuration with a maximum reverse voltage of 30 V and a peak reverse voltage of 35 V. Key electrical characteristics include a capacitance ratio of up to 23.2 at 1 MHz (VR = 1 V to 28 V) and a low series resistance of 0.85 Ω typical at 470 MHz. The component operates within a temperature range of -55 °C to 150 °C.

Feature Summary

Very high capacitance ratio suitable for wide tuning ranges
Low series resistance for improved signal integrity
Excellent uniformity and matching due to in-line assembly procedure

Applications

VHF TV tuners

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and marking details. Confirm RoHS compliance status and availability through authorized distributors. Ensure the component meets the required environmental specifications for the intended operating temperature range.

Selection Notes

Select this component when a high capacitance ratio and low series resistance are critical for VHF tuner performance. Consider the SC79 package dimensions for PCB layout constraints. Verify that the 30 V reverse voltage rating aligns with the circuit's maximum bias requirements.

Part Context

This part belongs to the BB689 series of silicon tuning diodes produced by Infineon Technologies. The series includes variants like BB669 and BB689-02V, offering different packages such as SOD323 and SCD80. These diodes are engineered for applications requiring precise capacitance control and matching.

Replacement Considerations

Check for direct substitutes within the BB689 series or other manufacturers' VHF tuning diodes with similar capacitance ratios and package footprints. Ensure any replacement matches the SC79 package outline and electrical characteristics specified in the datasheet.
