In this website, we already cover almost all topics related to transistor if like to read it then simply go to the “transistor” category section and read all articles related to the transistor. We try to explain all the points related to the basic transistor in easily digestible language.
here is some brief revision for the transistor. we also provide you all about transistors pdf / basic transistor pdf notes that you can download for offline reading.
briefly revision about transistor :
Here go with some brief revision about the transistor. We almost cover all transistor topics in previous tutorials here we will see in a brief explanation.
Transistors & their types :
The transistor is a three semiconductor current controlled device. There are mainly two types of transistors. PNP transistor and NPN transistor. Transistor has three terminals emitter, base, and collector. In the transistor, every three regions emitter, base, and emitter has a different width in the transistor.
PNP transistor – PNP transistor is made up of two p-type and one n-type semiconductor. Here n region is as a base region.
Npn transistor – NPN transistor is made up from two n-type semiconductors and one p-type semiconductor. Here p region is as a base region.

All the configuration of the transistor has some different input and output characteristics. Transistor configurations are used as per their applications in circuits. Common emitter configuration of the transistor is the most commonly used configuration. We already wrote separate articles related to these all configuration check out that also by clicking on above configuration links.
Applications of transistor :
Transistor is three terminal current controlled device and most used as switching operations. Transistors are widely used in amplifying circuits. They are mostly used as an amplifier and switch in circuits. There are also some decent applications of the transistor. We covered almost all applications related to the transistor in the previous article read that – Application of transistor
Transistor Vs. Vacuum tubes
In the past when the transistor was not invented then vacuum tubes are widely used. After the transistor invention, transistor replaced most of all applications of vacuum tubes. Transistor has some advantages and disadvantages over vacuum tubes. Transistor only operates for low power supply for high power supply applications vacuum tubes are used. We discussed in detail about the difference between the transistor and vacuum tubes check out – Transistor Vs. Vacuum tubes.

There are three main series of transistor codes used in the UK:
- Codes beginning with B (or A), for example BC108, BC478
The first letter B is for silicon, A is for germanium (rarely used now). The second letter indicates the type; for example C means low power audio frequency; D means high power audio frequency; F means low power high frequency. The rest of the code identifies the particular transistor.There is no obvious logic to the numbering system. Sometimes a letter is added to the end (eg BC108C) to identify a special version of the main type, for example a higher current gain or a different case style. If a project specifies a higher gain version (BC108C) it must be used, but if the general code is given (BC108 any transistor with that code is suitable.
- Codes beginning with TIP, for example TIP31A
TIP refers to the manufacturer: Texas Instruments Power transistor. The letter at the end identifies versions with different voltage ratings.
- Codes beginning with 2N, for example 2N3053
The initial '2N' identifies the part as a transistor and the rest of the code identifies the particular transistor. There is no obvious logic to the numbering system.
Choosing a transistor
Most projects will specify a particular transistor, but if necessary you can usually substitute an equivalent transistor from the wide range available. The most important properties to look for are the maximum collector current IC and the current gain hFE. To make selection easier most suppliers group their transistors in categories determined either by their typical use or maximum power rating.

To make a final choice you will need to consult the tables of technical data which are normally provided in catalogues.
They contain a great deal of useful information but they can be difficult to understand if you are not familiar with the abbreviations used. The table below shows the most important technical data for some popular transistors, tables in catalogues and reference books will usually show additional information but this is unlikely to be useful unless you are experienced. The quantities shown in the table are explained below.

Structure | This shows the type of transistor, NPN or PNP. The polarities of the two types are different, so if you are looking for a substitute it must be the same type. |
Case style | There is a diagram showing the leads for some of the most common case styles in the Connecting section above. This information is also available in suppliers' catalogues. |
IC max. | Maximum collector current. |
VCE max. | Maximum voltage across the collector-emitter junction. |
hFE | This is the current gain (strictly the DC current gain). The guaranteed minimum value is given because the actual value varies from transistor to transistor - even for those of the same type! Note that current gain is just a number so it has no units. |
Ptot max. | Maximum total power which can be developed in the transistor, note that a heat sink will be required to achieve the maximum rating. This rating is important for transistors operating as amplifiers; the power is roughly IC × VCE. For transistors operating as switches the maximum collector current (IC max.) is more important. |
Category | This shows the typical use for the transistor, it is a good starting point when looking for a substitute. Catalogues may have separate tables for different categories. |
Possible substitutes | These are transistors with similar electrical properties which will be suitable substitutes in most circuits. However, they may have a different case style so you will need to take care when placing them on the circuit board. |
