Brief description:

PN junction diode is a semiconductor device which is used as a switch, rectifier diode and square law modulator.

Diode is unidirectional device which works only in one direction.

Diode will allow current to flow only from p to n side of the PN junction diode.

Whenever current flows from n side to p side of the diode then this current is known as reverse saturation current.

Generally reverse saturation current is very small hence it is neglected.
