![]() ![]() In NPN three of the terminals are attached to each of the doped semi conductors. As transistors are three connection semiconductor devices. As we know that electrons are the majority carrier in NPN transistors, so the process of switching takes place rapidly in it than in the PNP transistors. NPN Transistor is the type of bipolar transistor consisting up of p-type semiconductor that is affixed in between two n-type semiconductors. In NPN n-type base is connected to the positive terminal. The p-type base is connected to the negative potential in NPN. Holes are the more important carriers in PNP transistor. PNP is the type of bipolar transistor consisting up of n-type semiconductor attached in between two p-type semiconductors.Įlectrons are the more important carriers in NPN transistor. The other most notable difference between two of them is that holes are the more important carriers in PNP transistors, while electors are the more important carriers in NPN transistor. NPN Transistor is the type of bipolar transistor consisting up of p-type semiconductor that is affixed in between two n-type semiconductors, whereas PNP is the type of bipolar transistor consisting up of n-type semiconductor attached in between two p-type semiconductors. BJT can further be divided into two types of transistors that can easily be differentiated. Unlike FET transistors, Bipolar Junction Transistors (BJT) are the current-controlled devices that are capable of current rectification. ![]() A transistor is the semiconductor device having three connections it is capable of amplification in addition to rectification. ![]()
