          Diode also called crystal diode, referred to as the diode (diode), in addition, there are early vacuum electronic diode; It is a kind of unidirectional conduction current electronic device. In a semiconductor diode internal have a p-n junction two lead terminal, the electronic device according to the direction of the applied voltage, with unidirectional current transduction sex. Generally speaking, crystal diode is a by p type semiconductor and n-type semiconductor sintering formation of p-n junction interface. Both sides of the interface in the formation of space charge layer, constitute a self-built field. When the applied voltage is equal to zero, because of p-n junction on both sides of the carrier concentration difference caused by diffusion current and self-built field caused by the drift current equal and in electric balance state, this is also the normal diode characteristic.
