Functions and characteristics of Schottky diodes

Functions and characteristics of Schottky diodes.

1. What is a Schottky diode.

Schottky diode (Schottky barrier diode): it is a low-power, ultra-high-speed semiconductor device with a very short reverse recovery time (which can be as small as a few nanoseconds). The voltage drop of the positive guide is only about 0.4V.

two。. Action characteristics of Schottky diodes.

The most important feature of Schottky diode is that the forward voltage drop VF is relatively small. In the case of the same current, its forward voltage drop is much smaller. In addition, its recovery time is short. It is often used as high-frequency, low-voltage, high-current rectifier diodes (such as switching power supply sub-pole rectifier diodes), continuous current diodes, protection diodes, and also used as rectifier diodes and small signal detection diodes in microwave communication circuits. It is common in communication power supply, frequency converter and so on.
