difference between NPN and PNP transistors

the fundamental difference between NPN and PNP transistors. transistors are electronic components made of semiconductors which are generally 3 feet each named base, collector, and emitter. In this article, admin will discuss difference between PNP and NPN transistors

Transistors in electronics circuits often function as amplifiers and switches. Transistors that we often encounter consists of 2 types of transistor type PNP and transistor type NPN

What is the difference between NPN and PNP transistors?

between both PNP and NPN transistors work in reverse. the PNP transistor will be active if on the base foot is given negative voltage while the NPN transistor will be active if the base is given positive voltage

Examples of PNP and NPN transistors which are pairs are 2N3055 transistors and MJ2955 transistors

The meaning of PNP is positive negative positive the meaning of NPN is negative positive negative

difference between PNP and NPN transistor

What is the difference between NPN and PNP transistors?. here is the basic difference between PNP and NPN transistors

  • on the PNP transistor times, the collector is always connected to the positive voltage whereas in the NPN transistor the collector’s foot is always connected to the negative voltage
  • the emitter foot of the PNP transistor will emit negative current while the NPN transistor outputs positive voltage
  • base legs on PNP transistors are controlled using negative voltages while in NPN transistors are controlled using negative voltages

how to easily determine the type of transistor whether the type of PNP or NPN

You can easily determine the leg of a transistor just by looking at where the leg of the transistor is connected

but before that you must know the exact location of base, collectors, and emittor

  • if collector’s foot is connected to negative voltage surely the transistor is a type of PNP
  • if the collector’s foot is connected to the positive voltage it must be an NPN type
  • if the emitter’s foot emits a negative voltage then it must be a PNP type transistor
  • if the emitter’s foot emits a positive voltage then it must be an NPN type transistor
  • if the base foot is controlled using negative voltage it must be a PNP transistor
  • if the base foot is controlled using a positive voltage it must be an NPN transistor
