![]() ![]() The structure is opposite to NPN transistor but similar in operation. The small Base current has the ability to control large Emitter current, as it is current controlled device. The current flow is due to the movement of holes. ![]() In PNP Transistors the electrons are minority charge carriers and holes are majority charge carriers. What is PNP TransistorĪ PNP Transistor is a type of Bipolar Junction Transistor which is composed of three layers where ‘N’ doped layer is sandwiched between two ‘P’ doped layers. This post provides a detailed information about PNP Transistor, how PNP transistor works, its characteristics, applications, advantages and disadvantages. It is used for functions such as amplification of signal, switches and oscillators. ![]() It is a basic transistor and often used in various electronic circuits. PNP Transistor is a sub-type of Bipolar Junction Transistors (BJT’s). ![]()
