With the emergence of PN junctions, several types of diodes also appeared for the most diverse applications. Thus, among the thousands of types of diodes existing in the world of electronics, there is the Schottky Diode, a semiconductor component, a type of diode widely used in high-frequency circuits that require a high working speed. The Schottky diode is an electronic component with operation based on the Schottky effect, which is named after the German physicist Walter Schottky. Botland.store offers a large variety of high-quality Schottky diodes from different manufacturers. If you need this product for your project, don’t hesitate to contact us and order a diode that will suit your expectations. Botland guarantees competitive prices and fast delivery.

Schottky Diodes - more information
Schottky diodes are the diodes with high switching speed and low voltage drop when directly polarized. Thus, this component can be used in applications where common diodes would not work as well, as it has a lower speed and a greater voltage drop. So, the voltage drop in the Schottky diode is usually in the microvolt household, while common diodes have voltage drops of approximately 0.7 volts, for components manufactured in silicon. In contrast, Schottky diodes do not withstand high temperatures and much less high voltages when inversely polarized.
How does the Schottky Diode Work?
The main difference between this component and the standard diode is its construction. Instead of using a junction with a type P semiconductor material, Schottky diode has metal in its construction. That way there is no layer with gaps in the component. This metallic layer is placed through chemical processes and is usually has oxide layer to avoid unwanted effects that a more intense electric field can cause. Because there are no gaps, there is no recombination of charges in the Schottky diode. Thus, its working speed is much higher than a common diode. The existence of metal in place of the type P material provides a much higher speed and less voltage drop. However, because there are no gaps, the reverse current in conduction is much greater.
Applications in audio systems
Common diodes, when applied to audio systems, can cause distortions in sound waves, due to their voltage drop. Since they don’t conduct direct polarizations with voltages less than the voltage drop, a good part of the audio signal will be lost. Thus, Schottky diodes can be used in audio systems to avoid distortions in sound waves. As audible signals also work at the most varied frequencies, the component is very suitable for working at higher frequencies. At Botland.store, you will find diverse, high-quality Schottky diodes perfect for audio systems. Check our catalog and buy the product that meets your needs.

Characteristics of the Schottky diode
Firstly, the Schottky diode has little capacity to conduct direct current (in the direction of the arrow). This feature doesn’t allow it to be used as a rectifying diode. There are rectification processes (for example power supplies) in which the amount of current that they have to conduct in a direct direction is quite large and exceeds the capacity of this diode.
Secondly, the Schottky diode doesn’t accept large voltages that reverse polarize it (VCRR).
The aforementioned rectification process also requires that the reverse voltage is large.
However, this diode finds many applications in high-speed circuits such as computers. High switching speeds are required in these applications and their low forward voltage drop causes low energy expenditure.
