The invention of the Bipolar Junction Transistor (BJT) is done in the year 1948. Transistors are the basic electronic devices that are formed because of the combination of the diodes that are referred to as bipolar junction transistor. These bought the revolutions in the modern electronic system. These inventions of transistors are the major reasons for the replacement of vacuum tubes. Individual diodes of the junction p-n that are connected back to back lead to the formation of the … [Read more...]
Uni Junction Transistor Working, Types and Applications
A Uni Junction Transistor (UJT) is a device that is formed with a single junction of p-type and the n-type of the semiconductor material. It resembles to that of the diode with a single junction of the P-N. It looks almost like that of the Junction Field Effect Transistor (JFET). But the operation is completely different in comparison with it. As the name suggesting it is a single junction transistor but it is widely used in the circuits of timing, triggering circuits and so on… it is a … [Read more...]
Transistor Configuration Types & Characteristics
Transistors are the basic equipment required for the formation of the devices. Hence the development of these transistors has been a replacement for the vacuum tubes. A basic transistor can be formed by the combination of the p-type semiconductor and the n-type semiconductor. This combination is sandwiched between one p-type and two n-types. The other combination is of two p-types and one n-type. Therefore N-P-N and the P-N-P transistors are formed. These transistors can be classified based … [Read more...]
Basics of Transistor, Working and Its Types
Transistors are also comes under the category of semiconductors. These are responsible for the revolutionary changes in the field of electronics. The first practical transistor was introduced in the year 1927 is known as point contact transistor by John Bardeen, Walter Brattain and William Shockley. The compression of the sizes of the electronic devices is only because of the invention of transistors.The word transistor can be split into two basic words. The very first one ‘trans’ is referred … [Read more...]
Basics of NPN Transistor – Construction & Its Working
NPN transistor is a type of bipolar junction transistor and it is the combination of two n-type and one p-type semiconductor. In this transistor, the p-type semiconductor is fixed in between both n-type semiconductors. Hence the two n-types are present in it. The majority of charge carriers of this transistor are electrons. This transistor includes three terminals namely emitter, base, and collector. The flow of the majority carriers in this type is from the emitter to the respective collector. … [Read more...]
Difference between Insulated Gate Bipolar Transistor (IGBTs) and High-Voltage Power MOSFETs?
In today's world there are wide varieties of solid-state, switch-mode, power-supply transistors to perform switching operations in power-electronic systems. All these have their own specifications in terms of current, voltage, switching speed, load, driver circuitry and temperature. Each one has its limitations and advantages as well, but its usage depends on the requirements of the application. … [Read more...]
Differences between NPN & PNP Transistors and their Making
Both p-n-p and the n-p-n transistors are the basic transistors which come under the category of bipolar junction transistors. These are used in the various amplifications circuits and the modulating circuits. The most frequent one among its applications is it’s fully ON and the OFF operating mode which is referred to as switch. NPN and PNP transistors are bipolar junction transistors, and it is a basic electrical and electronic component which is used to build many electrical and electronic … [Read more...]
