![]() ![]() Therefore, NPN transistors are preferred over PNP transistors. The electrons have better mobility than holes. The majority charge carriers in an NPN transistor are electrons and the majority carriers in a PNP transistor are holes. ![]() Why NPN transistor is preferred over PNP? So a npn transistor is faster in operation than a pnp transistor. The mobility of electrons is better than mobility of holes. An NPN transistor has a piece of P-type silicon (the base) sandwiched between two pieces of N-type (the collector and emitter).Ī npn transistor has electrons as majority charge carriers whereas the pnp transistor has holes as majority charge carrier. Depending on what is added to the silicon, it will be either N-type or P-type. NPN transistors are used in some classic amplifier circuits, the same as 'push-pull' amplifier circuits.Ī bipolar junction transistor is made up of three pieces of silicon. NPN transistors are used in applications we need sinking current. NPN transistors are used in the Darlington pair circuits for amplifying weak signals. NPN transistors are used in amplifying circuit applications. A negative-positive-negative transistor is denoted by the abbreviation NPN. In an NPN transistor, the flow of electrons is what causes it to conduct. It is a device that is controlled by the current. NPN transistors are a type of bipolar transistor with three layers that are used for signal amplification. PN2222A FAQ What is NPN transistor and its working? You can download the datasheet of PN2222A from the link given below: *Pulsed: Pulse duration = 300μs, duty cycle ≤ 2 % I C = 150 mA I B1 = - I B2 = 15 mA V CC = 30 V All are semiconductor devices made of silicon, a chemical compound found in the sand on a large scale.
