Bipolar Junction Transistors (BJTs) are widely used semiconductor devices for amplification and switching applications. A BJT consists of three layers of doped semiconductor material that form two PN junctions. These three regions are known as the Emitter, Base, and Collector. NPN and PNP are the two main types of Bipolar Junction Transistors. Unlike Field Effect […]

Zener Diode: Symbol, Construction, Working, Types and Applications
A Zener diode is a specially designed silicon semiconductor diode that is intended to operate in the reverse breakdown region. Unlike an ordinary PN junction diode, which is normally damaged when subjected to excessive reverse voltage, a Zener diode is manufactured with carefully controlled doping concentrations that allow it to safely operate in the breakdown […]

Extrinsic Semiconductors Explained
An extrinsic semiconductor is a semiconductor material whose electrical conductivity is intentionally increased by adding a small amount of impurity atoms into a pure semiconductor crystal. This process is known as doping. Extrinsic semiconductors form the foundation of modern electronics and are widely used in diodes, transistors, integrated circuits, LEDs, solar cells, and microprocessors. Pure […]
Difference Between SCR, DIAC and TRIAC
In power electronics, the SCR, DIAC, and TRIAC are three common semiconductor devices that are very useful in electric power control and conversion applications. Though they all belong to the thyristor family, their operation, structure, and applications differ significantly. Here’s a detailed explanation of SCR (Silicon Controlled Rectifier), DIAC (Diode for Alternating Current), and TRIAC […]
