The main characteristic of the diode is the unidirectional conductivity, which means that the resistance is very small under the action of the forward voltage. It is precisely because diode with the characteristics, the cordless telephone often put it in rectifier, isolation, regulator, protection, control code, FM modulation and squelch, etc. in the circuit. Crystal diode used in the use of the role can be divided into: rectifier diode (such as 1N4004), the isolated diode (such as 1N4148), Schottky diode (such as BAT85), light-emitting diode, voltage regulator diode, etc..
