What is the difference between Schottky diodes and other diodes?

The role of Schottky diodes in circuit applications is very obvious, and in what specific aspects is it reflected?

The biggest feature of Schottky diodes is their low forward voltage drop and short reverse recovery time. Schottky diodes have low turn-on voltage and small charge storage effect, making them suitable for high-frequency operation. Under the same current conditions, its forward voltage drop is much smaller than that of ordinary diodes. It also has the characteristics of low loss, low noise, high detection sensitivity, stability and reliability, and is used in microwave communication and radar for mixing, detection, modulation, frequency doubling, ultra high speed switching, low-noise amplification, etc.

The most obvious differences between Schottky diodes and ordinary diodes are as follows:

1. The forward conduction voltage drop of Schottky diodes is lower than that of ordinary diodes, so they have low power consumption.

2. Schottky diodes have a shorter reverse recovery time than ordinary diodes, so their operating frequency is higher.

3. The reverse withstand voltage of Schottky diodes is lower than that of ordinary diodes, generally below 200V.

4. Schottky diodes carry a stronger current than ordinary diodes.

5. Schottky diodes have a smaller junction capacitance than ordinary diodes.

6. Schottky diodes can pass high-frequency currents.
