BB 555 E7902

Overview

The BB 555 E7902 is a single varactor diode manufactured by Infineon Technologies, designed for voltage-controlled tuning applications. It operates within a maximum reverse voltage of 30 V and features a capacitance of 2.3 pF at 28 V reverse bias measured at 1 MHz. The device exhibits a capacitance ratio of 9.8 under test conditions from 1 V to 28 V. It is housed in an SCD-80 surface-mount package and supports a junction temperature range from -55 °C to +150 °C.

Feature Summary

• Single configuration varactor diode optimized for variable capacitance control
• High thermal stability supporting extended junction temperature ranges up to 150 °C
• Compact SCD-80 surface-mount packaging suitable for automated assembly

Applications

• TV and SAT tuner circuits
• Frequency modulation systems
• RF tuning networks

Procurement Notes

Verify component authenticity through official Infineon channels or authorized distributors. Confirm the specific suffix E7902 matches design requirements as it denotes tape-and-reel packaging. Check current lifecycle status as this part may be discontinued or subject to limited supply constraints.

Selection Notes

Select this component when a single varactor with a 30 V rating and approximately 2.3 pF capacitance at high reverse bias is required. Ensure the SCD-80 package footprint aligns with the PCB layout. Compare against the BB 565 series if different capacitance characteristics are needed.

Part Context

This part belongs to the BB 555 series of varactor diodes from Infineon. It shares functional similarities with other members like the BB 555 E7908 but differs in packaging and reel specifications. The series is commonly used in consumer electronics requiring precise frequency tuning.

Replacement Considerations

Publicly confirmed direct substitutes are not available in the provided data. Evaluate equivalent varactors from other manufacturers based on matching 30 V rating, SCD-80 package, and capacitance ratio specifications.
