Transistors Npn Pnp Basic Introduction Youtube This electronics video tutorial provides a basic introduction into npn and pnp transistors which are known as bjts or bipolar junction transistors. this vid. Npn transistors are three terminal, three layer devices that can function as either amplifiers or electronic switches. in the previous tutorial we saw that the standard bipolar transistor or bjt, comes in two basic forms. an npn ( n egative p ositive n egative) configuration and a pnp ( p ositive n egative p ositive) configuration.

There are two types of basic transistor out there: bi polar junction (bjt) and metal oxide field effect (mosfet). in this tutorial we'll focus on the bjt, because it's slightly easier to understand. digging even deeper into transistor types, there are actually two versions of the bjt: npn and pnp. we'll turn our focus even sharper by limiting. Npn and pnp refer to the arrangement of the pieces that make up the transister. the practical result is the direction of current flow. a bipolar junction transistor is made up of three pieces of silicon. depending on what is added to the silicon, it will be either n type or p type. an npn transistor has a piece of p type silicon (the base. Transistors are electronic devices that can be used as switches or amplifiers in circuits. npn transistors have two junctions and consist of n type and p type semiconductor materials. pnp transistors are the reverse of npn transistors, with two p type materials and an n type material.
Npn Transistor Model Npn and pnp refer to the arrangement of the pieces that make up the transister. the practical result is the direction of current flow. a bipolar junction transistor is made up of three pieces of silicon. depending on what is added to the silicon, it will be either n type or p type. an npn transistor has a piece of p type silicon (the base. Transistors are electronic devices that can be used as switches or amplifiers in circuits. npn transistors have two junctions and consist of n type and p type semiconductor materials. pnp transistors are the reverse of npn transistors, with two p type materials and an n type material. In an npn transistor, output current flows from the collector to the emitter. in a pnp transistor, output current flows from the emitter to the collector. below we go over the concepts explained above in more depth, with diagrams, to better illustrate the differences between npn and pnp transistors. voltage allocation and current flow are switched. The basic principles of operation of both npn and pnp transistors are the same. the only difference is in their basing and the power supply polarity for each type. in the npn transistor the current flows between the collector and the emitter when a positive supply is given to the base. but in the pnp transistor the current flows from emitter to.
