The BBY31 is a variable capacitance diode manufactured using planar technology and encapsulated in a SOT-23 small plastic SMD package. It is designed for applications requiring electronic tuning in UHF television tuners and Voltage Controlled Oscillators (VCOs).
Key electrical characteristics include a maximum continuous reverse voltage of 30V and a maximum continuous forward current of 20mA. The diode exhibits excellent linearity, with a typical capacitance ratio (Cd1/Cd2 at 8V/1V) of 8.3. At 1 MHz and a reverse voltage of 1V, the diode capacitance is typically up to 16.5 pF, while at 28V reverse voltage, it ranges from 1.6 to 2 pF. The diode series resistance is a maximum of 1.2 Ω at 470 MHz.
Operating temperature ranges from -55°C to +125°C, with storage temperatures between -55°C and +150°C. The component is suitable for surface mounting.
This component is identified by marking code S1.
