BBY5802WH6327XTSA1

Overview

The BBY5802WH6327XTSA1 is a silicon varactor diode manufactured by Infineon Technologies, designed for RF tuning applications. It features a dual common-cathode configuration housed in a compact SOT-323 (PG-SOT323) surface-mount package. The device supports a maximum repetitive reverse voltage of 10 V and operates within a temperature range of -55 °C to +150 °C. Key electrical parameters include a typical capacitance of 17.5 pF at zero bias and a minimum tuning ratio of 2.7 under specified test conditions. The component is qualified to AEC-Q100 standards, ensuring reliability for automotive environments.

Feature Summary

• Dual common-cathode structure for efficient circuit integration
• Automotive-grade qualification compliant with AEC-Q100 standards
• Compact SOT-323 surface-mount packaging for space-constrained designs

Applications

• RF tuning circuits in automotive infotainment systems
• Frequency modulation stages in wireless communication modules
• Voltage-controlled oscillator (VCO) implementations

Procurement Notes

Verify the specific ordering suffix against official Infineon documentation to confirm package type and tape-and-reel specifications. Confirm current lifecycle status as discontinuation notices may apply. Ensure compatibility with existing PCB footprints for the PG-SOT323 housing before finalizing procurement decisions.

Selection Notes

Select this component when a dual varactor configuration is required in an automotive RF environment. The SOT-323 package offers a balance between thermal performance and board space efficiency. Verify that the 10 V reverse voltage rating meets the peak operating voltages of the target application circuit.

Part Context

This part belongs to the BBY58 series of silicon tuning diodes from Infineon. The series provides various configurations including single and dual units in packages like SC-70 and SOT-323. The BBY5802 variant specifically denotes the dual common-cathode version, distinct from single-diode counterparts like the BBY5801 or other pin-compatible variants.

Replacement Considerations

Check for direct cross-reference parts within the BBY58 family. Verify pinout compatibility for SOT-323 packages. Consider alternative dual varactors if the specific tuning ratio or capacitance values of this discontinued unit are unavailable.
