What type of diode is Schottky diode

Schottky diode is a type of non conventional diode, named after the Schottky structure formed between P-type semiconductor and N-type metal.

The characteristics of Schottky diodes are fast switching speed and low turn-on voltage (forward voltage drop). It adopts a Schottky structure between metal and semiconductor instead of the conventional PN structure. In Schottky structures,

N-type metal comes into direct contact with P-type semiconductor, forming a metal semiconductor contact. The Schottky structure has the advantage of forming nonlinear current characteristics.

The working principle of Schottky diodes is that when a metal comes into contact with a P-type semiconductor, a Schottky barrier is formed, which can block the flow of current. When a forward voltage is applied, electrons move from the P-type semiconductor to

Metal diffusion generates an electric field, reducing the barrier height and allowing current to flow. When a reverse voltage is applied, the barrier height increases and the current can hardly flow.

Schottky diodes are widely used in high-frequency circuits and low-power applications, such as mixers, power amplifiers, switch circuits, etc. They have the advantages of fast switching speed, low reverse leakage current, and low power consumption, and are suitable for

Used for circuit applications that require high speed and efficiency.
