A diode is an electronic component that allows current to pass in one direction and blocks the current flow in the other direction. This phenomenon was discovered in 1874 by Ferdinand Braun at point contacts on lead sulfide. The term diode is usually applied for semiconductor diodes that operate with a P-N junction or a rectifying metal-semiconductor junction. In semiconductor technology, the term diode refers only to silicon diodes with a P-N junction, while other variants are identified by name with suffixes, for example Schottky diode or germanium diode. Diodes are used for rectification, the conversion of alternating voltage to direct voltage. In addition, the semiconductor junction has other useful properties which are exploited in Zener, photo and light-emitting diodes and semiconductor detectors. Diodes are the components, which are essential in the workshop of every electronics passionate and professional. In Botland store we have prepared a wide range of products, where everyone can find what they are looking for.
Diodes are common components in electronics and are used, among other things, to convert alternating current to direct current. LEDs have become incredibly popular because they are much more energy-efficient than traditional incandescent bulbs. Since the LED is a type of...
A rectifier diode is an electronic device, which is intended to convert a current to a constant current. It’s a two-electrode device, which has only one-sided (unipolar) electrical conductivity. A rectifier diode made of semiconductor materials and so-called diode...
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...
A Zener diode is a semiconductor diode that becomes strongly conductive for voltages above a given value, called the diode's Zener voltage. The Zener voltage applies to the blocking direction of the diode. In the conduction direction, the Zener diode behaves like a normal...

The first device capable of letting electric current pass in one direction while blocking it in the other, was discovered in 1874 by Karl Ferdinand Braun with a galena crystal. At the beginning of the 20th century, copper oxide or selenium rectifiers were used to convert alternating current to direct current. This use applied through most of the century to charging batteries. In 1901, Peter Cooper Hewitt invented the mercury vapor rectifier, which was used for power applications until the 1970s. At the same time, seeking to improve the detection of radio waves, John Fleming developed the first electron tube (the vacuum diode), whose heated cathode emits electrons that the anode can pick up, while the opposite is not possible. The germanium or silicon semiconductor diode replaced vacuum tubes after World War II. The development of semiconductors has led to the creation of many varieties of diodes, exploiting the characteristics of the P-N junction, or, in the case of light-emitting diodes, the ancillary properties of the material.
Despite its simple operation, the diode is a very useful component. Its primary function is to pass current in one direction only, while blocking it in the opposite direction. This phenomenon is called barrier polarization. Diodes are divided into different types, from the simplest to the most complicated devices. Advanced diodes work on the principle of non-linear current-voltage characteristics, which means that they can do more than just control the flow of current. It is also worth remembering that semiconductor diodes conduct electrical current when you exceed a threshold voltage in the direction of conductivity. Only temperature can affect the voltage drop of a diode, so this effect is used to measure it. In our offer we have prepared many diodes, which can meet the requirements of both professionals and amateurs.
