Diodes
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 - FAQ
A diode is a two-pin electronic element that conducts current in one direction (asymmetric conduction). It has very low resistance in one direction and high resistance in the opposite direction. Currently, the most commonly used semiconductor devices are silicon junction diodes, but the history of these elements dates back to electron tubes.
At Botland you will find rectifier diodes, Schottky diodes, Zener diodes and indicator lights. We have dedicated separate categories to LEDs and accessories. Diodes can be divided according to the material - early ones made of galenium and germanium, and currently the most widely used - silicon, due to their structure - connector, blade, Schottky or PIN, or due to their functions.
First of all, at the beginning you should determine what battery you will use (what kind of power it will provide). The resistance value of the resistor should be equal to the quotient of the difference between the battery voltage and the forward voltage in the diode and the diode forward current.
Provide a larger current that will flow through the diode - of course within a safe range so as not to burn it out, which is quite easy - and the brighter it will shine. The lack of the right resistor can damage the entire system, not just the diode!
