What Is Pn Diode?

A p–n diode is a type of semiconductor diode based upon the p–n junction. The diode conducts current in only one direction, and it is made by joining a p-type semiconducting layer to an n-type semiconducting layer.

What do you mean by PN diode?

A p-n junction diode is a basic semiconductor device that controls the flow of electric current in a circuit. It has a positive (p) side and a negative (n) side created by adding impurities to each side of a silicon semiconductor. The symbol for a p-n junction diode is a triangle pointing to a line.

What is a PN diode used for?

The PN junction diode is the basic semiconductor diode format. It is used for many forms of rectification for current levels both large and small, as well as high and low voltage levels, and this semiconductor device finds many uses in all manner of electronic circuit designs.
