Made of semi-conductor material and containing a p-n junction, it is designed to function in reverse bias. 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. The diode will conduct in only one case that is when the anode is positive regarding to cathode terminal. ... (PIN) diodes and avalanche photodiodes (APDs) to convert light to electrical current. Despite this it is still the most widely used form of diode, finding applications in audio CD players, and DVD drives, etc. A photodiode is a PN-junction diode that consumes light energy to produce an electric current. A diode is a specialized electronic component with two electrodes called the anode and the cathode.Most diodes are made with semiconductor materials such as silicon, germanium, or selenium.Some diodes are comprised of metal electrodes in a chamber evacuated or filled with a pure elemental gas at low pressure.
