What is an PN Junction Diode?PN Junction Diode A PN junction diode is a basic component in electronics. In this type of diode, one side of a semiconductor is doped with acceptor impurities (P-type) and the other side with donor impurities (N-type). This diode can be classified as either a ‘step graded’ or ‘linearly graded’ junction.In a step graded PN junction diode, the dopant concentration is uniform on both sides up to the junction. In a linearly graded junction, the doping concentration chan

What is a PN Junction?PN Junction DefinitionA PN junction is defined as an interface between p-type and n-type semiconductor materials in a single crystal.Make a PN JunctionLet us now examine how this pn junction is created. There are plenty of holes in p-type semiconductor and plenty of free electrons in the n-type semiconductor.Again in p-type semiconductor, there are numbers of trivalent impurity atoms, and ideally, each hole in the p-type semiconductor is associated with one trivalent impuri

PN Junction Diode DefinitionA PN junction diode is defined as a semiconductor device that allows current to flow in one direction in forward bias and blocks current in reverse bias.Forward BiasIn forward bias, the p-type region is connected to the positive terminal and the n-type to the negative terminal, reducing the depletion layer and allowing current flow.Reverse BiasIn reverse bias, the p-type region is connected to the negative terminal and the n-type to the positive terminal, increasing t
