Led pn junction diode. Difference between pn junction zener diode the major difference between pn junction and the zener diode is that the pn junction diode allows current to pass only in the forward direction whereas the zener diode allows the current to flow both in the forward and the reversed direction. Type Of All Kind Of Diode Zenzer Diode P N Junction Diode Double Heterojunction Light Emitting Diode Band Structure Schematic Of Charge Carrier Recombination At A P N Junction The led emits light. Led vs pn junction diode . In led all energy converted into a light. Led stands for light emitting diode so on the surface it may appear there is any different between the led and a common diode. The led uses gaas gaasp or gap material. The schottky barrier diode has electrons as majority carriers. In this article we will learn about what is a pn ...
