BB 565-02V E7902

Overview

The BB 565-02V is a silicon variable capacitance diode designed for UHF-TV tuners. It operates with a maximum reverse voltage of 30 V and a peak reverse voltage of 35 V. The device features a capacitance of 18.5 pF at 1 V and 1 MHz, dropping to 1.8 pF at 28 V and 1 MHz. It exhibits a minimum capacitance ratio of 9 (CT1/CT28) and a series resistance of 0.6 Ω at 470 MHz. The component supports an operating temperature range from -55 °C to +150 °C and is housed in the SC79 surface-mount package.

Feature Summary

High capacitance ratio for effective tuning
Low series inductance and resistance
Excellent uniformity due to in-line matching assembly

Applications

UHF-TV tuners

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and marking details. Confirm availability status as components may be discontinued or subject to change. Ensure compliance with RoHS requirements if lead-free packaging is required for the target application.

Selection Notes

Select this component based on its high capacitance ratio and low parasitic elements suitable for UHF frequencies. Consider the thermal operating range up to 150 °C and the single-diode configuration. Verify that the SC79 package dimensions align with the PCB layout constraints.

Part Context

This part belongs to the BB545/BB565 series of silicon varactor diodes manufactured by Infineon Technologies. The series includes variants like BB545 and BB565, differentiated primarily by their package types such as SOD323, SCD80, and SC79. These devices are engineered for applications requiring precise capacitance control in radio frequency circuits.

Replacement Considerations

Consult official Infineon documentation for verified substitute part numbers. Cross-reference electrical parameters such as capacitance ratios and reverse voltages when evaluating alternatives.
