Practical Electronics/Diodes/Types of diode

Diode's Types

Component	Diode	Description
Light Emitted Diode		Commonly used in lighting application where correctly applied voltage will turn on LED producing illuminations
Protection Diode		Used in a circuit to protect the circuit from reverse voltage and currents
Schottky Diode		A type of diode with low forward voltage ,Vf drop and a very fast switching ability. Used in almost all types of high-speed switching applications
Photo Diode		A type of special diodes that takes light energy and converts it into electrical energy
Varactor Diode		Primarily used in tuning circuits where a change in capacitance tunes the circuit
Zener Diode		Special type of diode that is used most extensively as a voltage regulator
Tunnel Diode		The characteristic of this diode is when voltage applied increases , the electric current decreases. It is used as a very fast switching device in computers
Shockley Diode		Functions primarily as a switch when applied voltages exceedingly the target voltage
