It is designed to exploit the changes in voltage dependent capacitance of a reverse biased p n junction therefore its ability to use junction barrier capacity has been improved.

Diode variable capacitance diode. Browse digikeys inventory of variable capacitance diodesvariable capacitance varicaps varactors. Varactor diodes or variable capacitance diodes are semiconductor diodes that have been optimized for the capacitance effect under reverse bias conditions. In practice radio frequency oscillations in the tracking filters can drive the single diode into conduction on peaks increasing the bias voltage and giving rise to.

Diodes whose junction capacitance is variable with voltage are beginning to replace large bulky tuning capacitors. Discrete semiconductor products ship same day. Features specifications alternative product product training modules and datasheets are all available.

The capacitance at the depletion region changes with the change in applied voltage. When reverse bias voltage applied to the p n junction diode is increased a large number of holes majority carriers from p side and electrons majority carriers from n side are moved away from the p n junction. Variable capacitance diode also known as varactor or tuner diode in a dab application.

Here are the operating principles and important parameters. Variable capacitance diode varicap diode also called varactor diode a special type of semiconductor diode. In electronics a varicap diode varactor diode variable capacitance diode variable reactance diode or tuning diode is a type of diode designed to exploit the voltage dependent capacitance of a reverse biased pn junction.

A varactor diode also called varicap vvc voltage variable capacitance or tuning diode is a type of semiconductor diode which features a variable voltage dependent capacitance on its p n junction when the device is reversed biased. Most textbook circuits show a single variable capacitance diode in place of the fsd270.
