BBY 66-05 E6327

Overview

The BBY 66-05 E6327 is a silicon tuning diode from the BBY66 series, manufactured by Infineon Technologies. It is housed in an SOT-23 package with a common cathode configuration and features a lead inductance of 1.8 nH. The device supports a maximum reverse voltage of 12 V and a forward current of 50 mA. At 1 MHz, the capacitance ranges from 66 pF to 71.5 pF at 1 V reverse bias, decreasing to approximately 12 pF at 4.5 V. The component exhibits a minimum capacitance ratio of 5 and a typical series resistance of 0.25 Ω at 470 MHz. It operates within a temperature range of -55°C to +150°C.

Feature Summary

High Q hyperabrupt tuning characteristic optimized for low tuning voltage operation
Very low capacitance spread ensuring consistent performance across units
Low series resistance suitable for high-frequency applications

Applications

Voltage Controlled Oscillators (VCOs) in mobile communications equipment
Low voltage tuner circuits
RF tuning applications requiring hyperabrupt capacitance-voltage characteristics

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and marking codes. Confirm RoHS compliance status and AEC-Q101 qualification requirements for automotive integration. Check for end-of-life notifications or discontinuation notices prior to finalizing procurement plans.

Selection Notes

Select this component when a hyperabrupt varactor with low series resistance is required for VCO designs. Ensure the operating voltage aligns with the specified 12 V reverse voltage limit. Consider the SOT-23 footprint constraints during PCB layout. Verify that the capacitance tolerance meets the circuit's frequency stability requirements.

Part Context

This part belongs to the BBY66 series of silicon tuning diodes designed for mobile communications. The series includes variants such as BBY66-02V and BBY66-05W, which differ in package types like SC79 and SOT-323. All variants share similar electrical characteristics but vary in physical dimensions and lead inductance values.

Replacement Considerations

Direct substitutes include other parts within the BBY66 series, such as BBY66-02V or BBY66-05W, provided the package and pinout compatibility are verified. Cross-referencing datasheets for capacitance ratios and series resistance is essential before implementation.
