Common emitter configuration of BJT
The common emitter circuit is probably the most widely used transistor configuration. The emitter electrode is common to both input and output circuits. The common emitter amplifier has a typical…
Difference between BJT and MOSFET
BJT and MOSFET are two types of semiconductor transistors. Even though both of them are transistors, they are different from each other in various aspects. By the end of this…
MOSFET – Structure, working principle, symbol and applications
A Metal Oxide Semiconductor Field effect transistors, commonly known as MOSFET, are semiconductor switching devices that have three terminals which are the gate, drain and source. They are unipolar transistors,…
Types of Transformer windings
Transformer windings constitute the electrical circuit of a transformer. They are made up of current-carrying conductors wound around the core. The primary windings form the input to the transformer and…
Insulation materials used in transformers
Insulation materials are one of the most important elements in a transformer. They are used to electrically separate the conducting parts of a transformer from each other and from other…
BJT – Bipolar Junction Transistors
Image credit: Michael Frey A Bipolar junction transistor, commonly known as BJT, is a Si or Ge semiconductor device that is structured like two p-n junction diodes connected back to…
Transformer core
A transformer core serves the following three important purposes: Provides mechanical support to the windings.Provides a low reluctance closed ferromagnetic path to the magnetic flux.Reduces the losses due to flux…
Transistors – Learn all about transistors
A transistor is an electronic semiconductor device that is used in the circuit to control, regulate and amplify electrical voltage or current signals. Nowadays, silicon is predominantly used as the…
Diode ratings – How to understand a diode datasheet?
Datasheets released by diode manufacturers contain a number of diode ratings. In order to select diodes for an application, it is important to understand all the ratings listed in the…
What is PIV rating in a diode?
PIV stands for 'Peak Inverse Voltage'. It refers to the maximum reverse bias voltage a semiconductor diode or other semiconductor devices can withstand without damaging themselves. The peak inverse voltage…
