A diode is a Electronic valve that has a cold anode and a heated cathode and whose use is intended for the rectification of current and electronic devices.
As a semiconductor device it will allow the passage of electric current only one direction and has the same characteristics as any switch.
Likewise, it is common that it is called a rectifier, since it is a device capable of suppressing that negative part that presents any signal, in beginning, and then transform a alternating current in a DC.
His functioning it is due to popular American inventor Lee De Forest, whose John fleming took some principles for creation.
The first diodes that appeared were valves or empty tubes called thermionic valves and that were built by means of two electrodes surrounded by vacuum in a tube of crystal, very similar to incandescent lamps.
Common applications of the diode include the following: half wave rectifier (is he circuit simpler than can be built with a diode, it removes the negative or positive part of an alternating current signal and transforms it into direct output current), r
full wave ectifier (It is a type of circuit that will use two or four diodes and unlike the previous one, it converts the positive alternating current signal into negative or vice versa), bender tension(using stages of diodes and capacitors converts voltage from a source of alternating current to another of direct current), Zener stabilizer (silicon diode that was named after its creator and that works in the breakdown zones), trimmer (reduces voltages at one point in the circuit), fixer circuit (they do not modify the input waveform but rather add a certain level of direct current), voltage multiplier (diode and capacitor networks that promote a very high direct voltage) and voltage divider (distributes the voltage of a source between one or more impedances that are connected in series).
