Originally they were made by placing a positively charged anode plate within view of a tungsten cathode in a high vacuum. By heating the cathode to ... we can form a PN junction; a diode.

Schematic Diagram of a P-N Junction Diode: The diagram illustrates the basic structure of a p-n junction diode with p-type silicon on one side, n-type silicon on the other, and the anode and cathode ...

LEDs form an inevitable part in the modern electronics as simple indicators to optical communication devices. Light Emitting Diodes exploit the property of the p-n junction to emit photons when it is ...

It has two points of contact, or terminals, called its anode and cathode. A diode’s primary purpose is to allow current to flow in only one direction. It achieves this using a p-n junction.

A conventional PN junction diode may have a voltage drop between 0.6-1.7 V, whereas the Schottky diode voltage drop is 0.15V ñ0.45V. A lower voltage drop permits a higher switching speed as well ...

Last week we covered diodes, specifically thermionic and PN junction diodes.But oh, there are more; and they’re special! One of the the most commonly used ‘specialty’ diode would have to be ...
