In present photonics technology, LASER diodes play an essential role. The term LASER stands for “Light Amplification by Stimulated Emission of Radiation". A Laser Diode is a p-n junction diode that emits laser radiation once the current is applied in forward direction. These diodes operate on the optical & electrical properties of semiconductor materials & PN junctions. The process used to emit coherent light in this diode is stimulated emission whereas, in light-emitting diodes, the … [Read more...]
What is Peak Inverse Voltage & Its Importance
In electronics engineering, different kinds of materials are used to carry electricity. The materials like copper, aluminum, germanium Ge), silicon (si) are good conductors of electricity and have good conductivity. Such materials are called semiconductors, used in various electronic applications. These types of materials have a narrow forbidden gap of 1eV, sufficient to transfer the electrons from the valance band to the conduction band. When two types of materials like p-type and n-type are … [Read more...]
Types of Break Down Diodes and Its Applications
The break down diode is an electronic component with two electrodes called as the anode and the cathode. Most of the diode is made up of semiconductor materials such as silicon, germanium etc. The fundamental property of a diode is to conduct electric current in only one direction and blocks the current that flows in the opposite direction. When the cathode is negative charge related to the anode at a voltage greater than minimum called as forward breaker, then the current flows through the … [Read more...]
What is a Varactor Diode : Working & Applications
In the digital electronic circuits, one of the basic essential devices is diodes. A diode consists of two terminals. These two terminals connected to the supply results in conduction. The way the terminal sare connected makes it classified as a forward-biased diode or reverse-biased diode. In forward bias, the diode allows the current to flow through it. During reverse bias, it blocks the flow of current. This reverse biasing is used in the case of the varactor diode. Based on the … [Read more...]
Zener Breakdown and Avalanche Breakdown
A diode is an electronic component that consists of two electrodes. These two electrodes are the positive electrode and the negative electrode. These diodes are composed of semiconductor materials like germanium, silicon, and selenium. The most important property of diodes is that they are capable of conducting current in one direction only. Diodes are used as voltage regulators, switches, rectifiers, etc. A PN junction diode is a type of diode that has a negative side (n) and a positive side … [Read more...]
What is Diode Approximations : Types & Its Problem
Diode Approximations are how the Diodes present in the circuit gets analyzed. The diode can be considered as the basic electronic device in any type of circuit. These are of various types a design criterion is based on the requirement. The analysis of it can be done based on the Three approximations. Each approximation can be done by considering the diode as a switching element. For these basic components called Diodes, there exist three approximations. In each one, the initial and the … [Read more...]
Zener Diode Working and Its Characteristics
A basic semiconductor diode can operate in forward bias but it cannot conduct during reverse bias. The special type of diode that can conduct in reverse bias is referred to as a Zener diode. This diode can conduct in forward bias just like a normal diode. The junction for the Zener diode will be heavily doped. Because of this reason, it can work as normally as a basic junction in forwarding bias and can tolerate the reverse currents during reverse bias. The main purpose of it is to use in … [Read more...]
Types of Diodes and their Applications
A basic diode consists of two terminals. This terminal is referred to as anode and cathode. It has a property of conducting the flow of current in a single and unified direction. This basic property of the diode makes it as a basic building block in the power supply units. because there it is preferred in the process of rectification. It is used during the modulation of the signals. There exist many uses for the diodes based on the requirements in various fields of electronics as well as … [Read more...]
Zener Diode as Voltage Regulator
A Zener diode is a type of semiconductor diode. Generally, a normal diode with p and n junction will not function or blocks the flow of the charge carriers’ results in no flow of the current is seen during the reverse biasing of the device. Hence this condition is known as Breakdown. The main purpose of designing this device is to make the device to conduct in the reverse biasing condition. It can normally function just like a diode with p-n junction in forwarding biased condition. In this type … [Read more...]
