[0002] As we all know, a diode is an electronic device made of semiconductor materials (silicon, selenium, germanium, etc.). A diode has two electrodes, the positive electrode, also called the anode, and the negative electrode, also called the cathode. When a forward voltage is applied between the two electrodes of the diode, the diode is turned on, and when a reverse voltage is applied, the diode is turned off. The conduction and cutoff of a diode are equivalent to the on and off of a switch.
