Overview
The BBY 66-02V E6327 is a silicon hyperabrupt tuning diode manufactured by Infineon Technologies in an SC-79 surface-mount package. It features a maximum reverse voltage of 12 V and a forward current rating of 50 mA, with an operating temperature range from -55 °C to +150 °C. At 1 MHz and 1 V reverse bias, the capacitance ranges from 66 pF to 71.5 pF depending on the specific group, yielding a typical capacitance ratio of 5.41 between 1 V and 4.5 V. The series resistance is typically 0.25 Ω at 470 MHz.
Feature Summary
- Hyperabrupt junction design optimized for low tuning voltage operation
- High Q factor suitable for mobile communications equipment
- Very low capacitance spread for precise frequency control
- Qualified according to AEC-Q101 automotive standards
Applications
- Voltage Controlled Oscillators (VCOs) in mobile communications
- Frequency synthesizers requiring high linearity
- Low noise tuners for RF systems
Procurement Notes
Verify component authenticity through authorized channels as counterfeit components exist. Confirm the specific capacitance group (01 or 02) required for your circuit design, as these are not directly selectable during ordering. Ensure the SC-79 footprint matches your PCB layout constraints before finalizing procurement.
Selection Notes
Select this component when a hyperabrupt varactor with high Q and low series resistance is needed for VCO applications. Compare against the BBY 66-05 if a SOT-23 package is preferred. Verify that the 12 V reverse voltage rating meets the peak reverse voltage requirements of your tuning circuit.
Part Context
This part belongs to the BBY66 series of silicon tuning diodes. Other variants include the BBY66-05 in SOT-23 and the BBY66-05W in SOT-323 packages. All share similar electrical characteristics but differ in physical dimensions and lead configurations.
Replacement Considerations
Direct replacements within the same family include BBY66-05 (SOT-23) and BBY66-05W (SOT-323). Cross-brand equivalents require matching the hyperabrupt profile, capacitance range, and Q factor at the operating frequency.
