The PN junction diode is one of the most important and widely used semiconductor devices in electronics. It is created by joining a P-type semiconductor and an N-type semiconductor within a single crystal structure. This simple yet powerful device allows electric current to flow easily in one direction while offering very high resistance to current […]
Diodes
In this blog we will be discussing about different types of diode and symbol. A diode is basically two terminal electronic device which allows current to flow in one direction while it blocks the current in other direction.
It is made of two types of semiconductor materials namely p-type and n-type. By varying the properties of these materials different types of of diode are manufactured. Here are some different type of diodes described as follow.
Schottky diode
PN junction diode
Avalanche diode
Zener diode
Light Emitting Diode
Photodiode
Laser diode
Drift Current and Diffusion Current in Semiconductors
Drift current and diffusion current are two fundamental mechanisms of charge transport in semiconductors. These concepts form the basis of semiconductor physics and are extremely important for understanding the operation of devices such as p-n junction diodes, transistors, LEDs, solar cells, MOSFETs, and integrated circuits. In semiconductors, electric current is produced not only by the […]
Types of Diodes: Symbol, Working, Characteristics and Applications
Diode is a versatile electronic component, many specialized types of diodes exist, each optimized for specific applications such as voltage regulation, light emission, high-speed switching, and detection. It is one of the most fundamental semiconductor devices used in electronics. It plays a critical role in controlling the direction of current flow in a circuit. From […]
Rectifier Circuit: Construction, Working, Types and Applications
A rectifier is an electronic circuit or device that converts Alternating current (AC) into Direct current (DC) by allowing current to flow in only one direction, typically using semiconductor components such as diodes or controlled devices like thyristors. It enables AC-powered sources to operate devices that require a stable unidirectional DC voltage. This conversion is […]
Power Diode: Symbol, Construction, Working, Types and Applications
A power diode is a semiconductor device specifically engineered to conduct large currents and withstand high reverse voltages in power electronic circuits. It is fundamentally a PN junction diode, but its internal structure, doping profile, and packaging are optimized for high-power operation rather than low-level signal processing. In power electronic systems, power diodes play a […]
TVS Diode: Symbol, Construction, Working, Types and Applications
A TVS (Transient Voltage Suppression) diode is a specialized semiconductor device used to protect electronic circuits from high-voltage transients such as electrostatic discharge (ESD), lightning surges, and switching spikes. It responds extremely fast and clamps overvoltage to a safe level before they damage sensitive components. Modern electronic systems are highly sensitive to voltage spikes caused […]
