BBY5806WH6327XTSA1

Overview

The BBY5806WH6327XTSA1 is a dual varactor diode manufactured by Infineon Technologies, housed in an SC-70 or SOT-323 surface-mount package. It features a common anode configuration with a maximum peak reverse voltage of 10 V and a typical capacitance of 5.5 pF at 6 V reverse bias and 1 MHz frequency. The device exhibits a capacitance ratio of 3.5 under C1/C4 conditions. It operates within a junction temperature range of -55°C to +150°C. This component is classified as end-of-life.

Feature Summary

• Dual varactor structure with common anode topology for compact circuit integration
• Capacitance tuning capability defined by specific reverse voltage and frequency parameters
• Automotive-grade qualification ensuring reliability in demanding environments

Applications

• RF tuning circuits requiring variable capacitance control
• Voltage-controlled oscillator (VCO) frequency adjustment stages
• Impedance matching networks in radio frequency systems

Procurement Notes

This component has reached the end-of-life status according to manufacturer notifications. Verification of final purchase orders should confirm availability through authorized distributors or secondary market suppliers. Designers must assess long-term supply risks and initiate replacement strategies immediately to ensure production continuity.

Selection Notes

Engineers selecting this part should verify the 10 V reverse voltage limit and 5.5 pF baseline capacitance against circuit requirements. The common anode configuration dictates specific biasing schemes. Due to the end-of-life status, alternative components from the same family or newer generations should be evaluated for compatibility with existing PCB footprints and electrical specifications.

Part Context

The BBY5806WH6327XTSA1 belongs to the BBY58 series of varactor diodes from Infineon Technologies. These devices are designed for RF applications where variable capacitance is required for tuning purposes. The SOT-323 packaging allows for high-density mounting on printed circuit boards, suitable for consumer electronics and automotive communication modules.
