Jan 12, 2024 · A varactor diode, also known as a Varicap or volt-cap, is a type of PN junction diode primarily utilized in the reverse-biased mode. It is a device whose capacitance varies with the variation in the applied reverse bias potential. The term “Varicap” originates from the fusion of the words “variable” and “capacitor.”.
Varactor diode is a type of diode whose internal capacitance varies with respect to the reverse voltage. It always works in reverse bias conditions and is a voltage-dependent semiconductor device. Several names know varactor diode as Varicap, Voltcap, Voltage variable capacitance, or Tunning diode.

Feb 24, 2012 · A varactor diode is defined as a reverse-biased p-n junction diode whose capacitance can be varied electrically. These diodes are also known as varicaps, tuning diodes, voltage variable capacitor diodes, parametric diodes, and variable capacitor diodes.
Definition: Varactor Diode is a PN junction diode that is especially operated in reverse biased mode. It is a device whose capacitance varies with the variation in the applied reverse bias potential.
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 p–n junction.
A varactor diode is a reverse-biased junction diode whose mode of operation depends on its capacitance. When a p-n junction diode is reverse-biased, the depletion region acts as a capacitor dielectric.
The varactor diode is a device used in situations where variable capacitance is required, which is controlled by applying voltage. This type of diode is also known as a varicap, voltcap, voltage variable capacitance, or tuning diode.
Sep 28, 2009 · A varactor (or a tuning diode) is a diode designed to be used as a voltage controlled capacitor. A diode starts as a piece of intrinsic mono-crystalline material. Intrinsic means it contains no atoms of other material. Mono-crystalline means its one single crystal with all the electrons trapped in covalent bonds between atoms.
Apr 25, 2024 · What is a varactor diode? Variable capacitors like air capacitors and trimmer capacitors are adjustable manually. In contrast, the capacitance of a varactor diode is controlled by a reverse bias voltage. Since the controlling voltage can be applied automatically, manual tuning is no longer required.
