WebDefinition: NPN transistor is a type of bipolar transistor that has 3 layers and is used for signal amplification. It is a current controlled device. NPN is an abbreviation used for a negative positive negative transistor. This means a p-type semiconductor is fused between 2 n-type semiconductor material. WebIn NPN transistor electron flow from Emitter to the collector. So conventional current flow from collector to emitter. Electrons from the emitter region flow towards the base region constitute emitter current (I E ). Electrons after reaching the base region recombine with holes – Most of the electrons reach the collector region. WebIn an NPN transistor, 108 electrons enter the emitter in 10-8s.
