Importance of transistor
A transistor is an electronic device invented in 1928 by Julius Edgar Lilienfeld. It was the first field effect transistor developed over time with the advancement of science. The main use of this component is to amplify, disconnect and connect signals. Most transistors are made of conductive materials called silicon and germanium, which are solid state devices. Each transistor has two connections in its structure, which are the N-type connection and the P-type connection. The performance of each type of transistor is different and they are used in a specific place. It is possible to buy any original transistor you need from Yougou Electronics in the shortest possible time and wholesale price.
Types of Transistor
In general, transistors are divided into two categories, one of which is bipolar junction transistors (BJT) and the other is field effect transistors (FET). Generating current in the dipole connection type and generating voltage in the field effect type between the input and the common terminal will increase the output conduction level and the common terminal, which will control the current intensity by the transistor. In each transistor, different specifications are recorded, which in most cases go back to their type. Their appearance varies according to their frequency and working power.
The important point is that the field effect transistors themselves are divided into two categories, which are field-effect link transistors (JFETs) and metal-oxide semiconductor field-effect transistors (MOSFETs). In the following, you will get acquainted with the types of transistors.
Bipolar Junction Transistor (BJT)
In bipolar junction transistors, the current enters to the base and is controlled from both the collector and emitter bases. These bipolar junction transistors are made in two types PNP and NPN. The operation of these transistors in the off, active or saturated region depends on the bias mode. Due to the high speed of these transistors, their use in special circuits has increased. For example, today in circuits, the use of transistors is more than capacitors and resistors.
Junction Field Effect Transistor (JFET)
In JFET transistors, the amount of current between the source and output terminals is controlled by applying voltage to the input terminal. There are two types of field effect transistors, N-type and P-type. Other types of transistors are made with incremental and discharge methods. Active, saturation and triode are the working areas of these transistors, and due to current limitation, they are rarely used.
Types of junction transistors
The PNP transistor has three semiconductor layers, two P-side sidewalls and two N-intermediate layers, which are designed to flow holes with a flow direction. NPN transistors have three semiconductor layers, two N-side layers and two P-middle layers.
Transistor applications
All electronics experts know that a transistor is a very useful and important component, so it is called the heart of electronics. Transistors are generally used in analog and digital electronic circuits. Transistors operate in analog circuits and can be used as amplifiers or voltage stabilizers. They are used in digital circuits in both cut-off and saturation regions. In these areas, it can be used to implement logic circuits, memory and switches.
Advantages of Using a Transistor
Transistors have many advantages in the electronics industry and have more applications than other electronic components. Some of these benefits are:
- Transistor is High voltage
- Transistor requires low voltage to work
- Transistor is low in power consumption
- Transistor has small dimensions and low weight
- Transistors are Mechanically very strong and strong compared to vacuum tubes
- Transistor Requires less heat than vacuum tubes
Why Buy Transistors from China?
