توضیحات
گاهي در مدار هاي الکترونيکي نياز هست جريان الکتريکي در يک جهت جاري شود. و در جهت ديگر جرياني جاري نشود (مدار باز). در اين مواقع از قطعه اي در مدار استفاده مي کنيم، به نام ديود. Diode را مي توان به دريچه دهليز قلب تشبيه کرد. دريچه دهليز قلب خون را از يک جهت هدايت کرده و از سوي ديگر مانع عبور خون مي شود. Diode هم جريان الکتريکي را از يک سو عبور مي دهد. و از سوي ديگر مانع عبور جريان مي شود.
Description
(3A at 1000V) A diode is a two-terminal electronic component that conducts current primarily in one direction (asymmetric conductance); it has low (ideally zero) resistance in one direction, and high (ideally infinite) resistance in the other. A diode vacuum tube or thermionic diode is a vacuum tube with two electrodes, a heated cathode and a plate, in which electrons can flow in only one direction, from cathode to plate. A semiconductor diode, the most commonly used type today, is a crystalline piece of semiconductor material with a p-n junction connected to two electrical terminals. Semiconductor diodes were the first semiconductor electronic devices. The discovery of asymmetric electrical conduction across the contact between a crystalline mineral and a metal was made by German physicist Ferdinand Braun in 1874. Today, most diodes are made of silicon, but other materials such as gallium arsenide and germanium are used.
