Best Answer

It is a semiconductor device with two terminals, typically allowing the flow of current in one direction only. It may also be termed as the electronic component with two electrodes known as the anode and the cathode. Most diodes are made with semiconductor materials such as silicon, germanium, or selenium. The diode acts as a valve in the electronic and electrical circuit.

How do you test a diode?

To test an ordinary semiconductor diode use a multimeter to verify that it conducts in one direction but not in the other. Testing of other types of diodes (e.g. zener diode, tunnel diode, gunn diode, Peltier heat pump diode, photodiode, PIN diode, varactor diode, light emitting diode, LASER diode, vacuum tube diode) is more complicated and often requires special test equipment unique to that type of diode.

What are the differences between a light emitting diode and a semiconductor diode?

The primary difference is that a semiconductor diode is a diode with a p-n junction, and a light-emitting diode is a special case or special type of semiconductor diode that emits light when it is forward biased.


What is the difference between electric diode and electronic diode?

Not sure of your context. A diode is a diode. One artificial distinction might be that an electric diode refers to a diode used in a higher power application with more current where an electronic diode might be found on a circuit board as part of an electronic lower power application.
