Common Cathode Structure Schottky Diode For Polarity Protection Applications​

MBR10200.pdf

A Schottky diode is a metal-semiconductor device made of a noble metal (gold, silver, aluminum, platinum, etc.) A as the positive electrode and an N-type semiconductor B as the negative electrode, and the potential barrier formed on the contact surface of the two has rectification characteristics. Because there are a large number of electrons in the N-type semiconductor and only a small amount of free electrons in the noble metal, the electrons diffuse from B with high concentration to A with low concentration. Obviously, there are no holes in metal A, and there is no diffusion of holes from A to B. As electrons continue to diffuse from B to A, the electron concentration on the surface of B gradually decreases, and the surface electrical neutrality is destroyed, thus forming a potential barrier, and its electric field direction is B→A. However, under the action of the electric field, the electrons in A will also produce a drift motion from A→B, thus weakening the electric field formed due to the diffusion motion. When a space charge region of a certain width is established, the electron drift movement caused by the electric field and the electron diffusion movement caused by different concentrations reach a relative balance, forming a Schottky barrier.
