What is an example of a diode?
An example of a diode is a light-emitting diode, an LED. A two-terminal semiconductor device, having a p-n junction, used chiefly as a rectifier. An electronic device that restricts current flow chiefly to one direction.
Which is an example of pn junction diode Mcq?
For example: Silicon, Germanium, etc. The semiconductor device which is used to control the flow of electric current is called as p-n junction diode.
What kind of device is pn junction diode?
A p-n junction diode is two-terminal or two-electrode semiconductor device, which allows the electric current in only one direction while blocks the electric current in opposite or reverse direction. If the diode is forward biased, it allows the electric current flow.
Which is an example of pn junction diode Sanfoundry?
8. Which is an example of PN junction diode? Explanation: Light Emitting Diode (LED) is an example of PN junction diode.
What is meant by PN junction diode?
Definition: A P-N junction is an interface or a boundary between two semiconductor material types, namely the p-type and the n-type, inside a semiconductor. The p-side or the positive side of the semiconductor has an excess of holes and the n-side or the negative side has an excess of electrons.
What are the applications of pn junction diode?
Applications of PN Junction Diode It can be used as a solar cell. When the diode is forward-biased, it can be used in LED lighting applications. It is used as rectifiers in many electric circuits and as a voltage- controlled oscillator in varactors.
What is PN junction diode?
A PN Junction Diode is one of the simplest semiconductor devices around, and which has the electrical characteristic of passing current through itself in one direction only. However, unlike a resistor, a diode does not behave linearly with respect to the applied voltage.
What devices use PN junction?
Junctions between p-type and n-type semiconductors are used to make solar cells, photodiodes, light-emitting diodes, and laser diodes.
What is application of PN junction diode?
Application of PN Junction Diode It can be used as a solar cell. When the diode is forward-biased, it can be used in LED lighting applications. We can see that it is also used as a rectifier in many electric circuits and as a voltage-controlled oscillator in varactors.
Where we use PN junction diode?
Due to above fact, PN junction diode has many applications as outlined below. It is used in clipping circuits as wave shaping circuits in computers, radios, radars etc. It is used as switches in digital logic designs. It is used in detector and demodulator circuits.
How many types of PN junction diodes are there?
There are two kinds of Photodiodes – PN and PIN photodiodes. The difference is in their performance. The PIN photodiode has an intrinsic layer, so it must be reverse biased. As a result of reverse biasing, the width of the depletion region increases, and the capacitance of the p-n junction decreases.
