Varactor Diode Schematic Symbol

- February 07, 2019

It has two electrodes called anode or plate and cathode it uses the rectifying properties of the union between type p and n materials of a semiconductor. Some of the major types of diode include the pn junction schottky varactor zener or avalanche reference diode photo diode light emitting diode.

Varactor Diode Working Characteristics And Its Applications

What Is A Varactor Diode Working And Characteristics

Varactor Diode Construction Working Characteristics

The circuit symbol of the varactor diode is almost similar to the normal p n junction diode.

Varactor diode schematic symbol. The diode is a semiconductor device that allows the current to flow in one direction only. The symbol of a varactor diode is shown in the below figure. Two parallel lines at the cathode side represents two conductive plates and the space between these two parallel lines represents dielectric.

A number of schematic symbols are used to represent a varactor diode in circuit diagrams. It is a device whose capacitance changes with the variation in the applied reverse bias potentialit is also known as varicap or voltcap. Among these three symbols of a varactor diode the second symbol is more frequently used.

A varactor diode is a pn junction diode that is especially operated in reverse biased mode. The symbol of the varactor diode is shown in the above figure that includes a capacitor symbol at one end of the diode that signifies the characteristics of the variable capacitor of the varactor diodes. Schottky diode is a diode with low voltage drop.

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. The symbol of the varactor diode looks like a common pn junction diode that includes two terminals namely the cathode and the anode. Varactor or varicap circuit symbol the varactor diode or varicap diode is shown in circuit diagrams or schematics using a symbol that combines the diode and capacitor symbols.

Light emitting diode led. The word varicap is originated from the combination of word variable and capacitor. It is a combination of symbol of a p n junction diode and a capacitor.

Diode allows current flow in one direction only left to right. The one end of a symbol consists the diode and their other end has two parallel lines that represent the conductive plates of the capacitor. The diode has two terminals namely anode and cathode.

There are many different forms of diode and for most types there is a distinct circuit symbol. Allows current flow in one direction but also can flow in the reverse direction when above breakdown voltage. Varactor varicap diode.

In this way it is obvious that it is being used as a variable capacitor rather than a rectifier. The symbol of the varactor diode is similar to that of the pn junction diode. Of them the three most popular representations are shown below.
