Diodes definition and applications(introduction)

What is Diode?

a semiconductor device with two terminals, typically allowing the flow of current in one direction only.

a thermionic valve having two electrodes (an anode and a cathode).

Diode has a wide variety of applications in modern electronic systems.

Diodes and Light

An LED flashlight is just a flashlight whose illumination is sourced from a light-

emitting diode. In the presence of positive voltage, LEDs glow.

A photodiode, by contrast, accepts light through a collector (like a mini solar 

panel) and converts that light into a small amount of current.

Some Diodes applications

•Mixing signals

•Isolating signals from a supply

•Rectifying a voltage, such as turning AC into DC voltages

•Controlling the size of a signal

Common types of Diodes

•Normal Diodes

•Light Emitting Diode (LED)

• Schottky Diode

•Zener Diodes

•Photodiodes

In next post, we will discuss how did we make the diode and the types of 

connections, follow us & stay tuned!!!!
