An NPN Transistor is a type of three-terminal bipolar junction transistor (BJT) that is formed with one p-type semiconductor material by sandwiching in between two N-type semiconductor materials. In this type of transistor, the majority of charge carriers are electrons and the minority charge carriers are holes. The main function of this NPN transistor is to amplify the weak signal that is entering the base terminal & generate strong signals at the collector terminals. The direction of … [Read more...]

An SMD transistor is a surface-mount device transistor that can be directly soldered onto the surface of a PCB. The transistors which can be mounted in this way can detach more easily, so the circuit boards which use SMD transistors are very cheaper to produce as compared to others. These transistors are made up of semiconductor materials like Germanium/ Silicon. There are two kinds of SMD transistors like PNP type & NPN type and these transistors are marked with some codes to indicate the … [Read more...]

Transistors are semiconductor devices mainly used for switching or amplifying electrical signals & power. In modern electronics, these components are basic building blocks that include a minimum of three terminals for connecting in an electronic circuit. Transistors are generally classified into three types like BJTs, FETs & IGBTs. These transformers are also available in different types based on different functions like small switching, small-signal, power, phototransistor, UJT & … [Read more...]

2n5401 PNP transistor is used in different general-purpose electronic applications. These transistors are very helpful wherever the load is connected with the transistor and consume low current, although it works on high voltage. This PNP transistor can also be used frequently in telephone circuits, or any electronic circuits wherever you desire to build a simple switching application (or) amplification with high voltage. This transistor is also used as a general-purpose transistor to control … [Read more...]

A semiconductor device like a transistor is one of the basic building blocks within modern electronics mainly used for switching or amplifying electrical signals & power whereas the Darlington transistor has a multi-transistor configuration that performs like a single transistor that includes one base, emitter & collector. This Darlington configuration has a higher current gain as compared to every transistor taken independently. So it works & frequently packaged as a single … [Read more...]

A type of transistor that is designed by sandwiching an N-type semiconductor between the two P-type semiconductors is known as a PNP transistor. This transistor includes three terminals like collector, emitter & base. This transistor performs as two PN junction diodes connected end-to-end. These end-to-end PN junction diodes are called the collector-base (CB) junction & base-emitter (BE) junction. There are different PNP transistors which are manufactured by different manufacturers like … [Read more...]
