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.
