A diode is an electronic component with two terminals that conduct asymmetrically. Although there are different types of diodes with different invention histories, the thermionic diodes were first described by Frederick Guthrie in 1873.

What is formula for zener diode comparator?

A: There is no formula it is a comparison of the zener diode voltage to the other input when one exceed the other the comparator will change state on the output and decreasing will return to the previous state


How does a quenching diode work?

Quenching diodes are used to protect the control circuit of a relay. Power is applied to a relay's coil to close it. When this power is released there is a backwards flowing pulse that can wipe out solid state devices like transistors, LEDs, chips, etc... The quenching diode is applied in parallel with the relay coil so that the cathode is on the positive side. During normal operation, the diode doesn't conduct and the relay operates normally. When the relay is switched off, the "reversed" back pulse is absorbed due to the low voltage drop of the diode which limits the spike.


What happens when the diode is reversed in the circuit?

When a diode is reversed in a circuit, it becomes reverse-biased, blocking current flow. In this state, the diode prevents current from passing through, effectively acting like an open switch. If the reverse voltage exceeds the diode's breakdown voltage, it may enter a breakdown region, potentially damaging the diode unless it is designed to handle such conditions. Otherwise, under normal reverse bias, the diode will simply not conduct.

What is the solid state diode?

A solid-state diode is a semiconductor device that allows current to flow in one direction only. It consists of a p-n junction where the movement of charge carriers across the junction creates the diode's characteristic behavior of allowing current to flow when forward biased and blocking it when reverse biased. Solid-state diodes are widely used in electronics for rectification, signal modulation, and switching applications.


What are Three types of Lasers?

Gas,solid state,diode The first laser was a solid state laser. Solid state refers to any solid material like a glass rod. Diode lasers are very common because they are used to read compact disks and digital video disks in computers, CD players, and DVD players. Before diode lasers, the most common type of laser may have been the helium-neon laser, in which the active medium is a combination of the two gasses helium and neon.

What is the difference between solid state laser and semiconductor laser?

LASER is Light amplification by stimulated emission of radiation. As far as I have understood, Solid State laser is a macroscopic form of diode laser. Thus a small semiconductor diode is similar to a solid state laser except for the mechanism of lasing and size.


Does diode make noise?

There are diode tubes that can make noise, but they have not been popular for a number of decades. The solid-state diodes that you find on printed-circuit boards have no moving parts, so are silent, unless they have been damaged in some way.
