Hello, electronic students welcome to new post. We will discuss Introduction to BC108 NPN Transistor. The transistor is a general-purpose electronic component used in different projects and circuits as amplifiers and switches. It comes with three pinouts EMitter, base, and collector. The transistor has two configurations NPN and PNP. In the PNP transistor, there are two P regions doped with hole carriers; in N, electrons are charge carriers.
Potential barriers exist in the transistor that is crossed by the holes and electrons to make the conduction. In this post we will discuss BC108 NPN Transistor pinouts, working, and applications.
Introduction to BC108 NPN Transistor
- BC108 transistor is a semiconductor module that is mostly used in such circuits where amplification is needed as well as power amplification and is employed as a switch.
- It is an NPN configured transistor and uses a small quantity of input supply volts are the base so the needed current passes in the transistor.
- Before use of this transistor in amplification circuits must check the gain value from the datasheet of the transistor.
- Since the different value of gain is given by the different manufacturers must note this before the application of these components.
- The highest value of collector current for this transistor is two hundred milliamperes and VBE is five volts.
- Since this transistor, if NPN is configured so there are two N regions and one P region.

Working of a BC108 Transistor
The BC108 transistor is general purpose NPN transistor, the junction transistor is but between two layers of N or P materials. Based on the structure transistor comes with two types NPN transistors and PNP transistors
For an NPN transistor electrons operate as primary charging components and are released from the emitter of the transistor to the PN junction.
If positive voltage is connected with holes is produced at the base and moves to emitter junctions. That process reduces the size of the depletion region of the PN junction and more electrons flow and get at collectors.
