In electronics, a diode is a two-terminal electronic component with an asymmetric transfer characteristic, with low (ideally zero) resistance to current flow in one direction, and high (ideally infinite) resistance in the other. Definition of a PIN Diode. That is the current should always flow from the Anode to cathode. It turns off very quickly when the forward voltage stops. it helps in fast switching due to the time delay in removing the stored charges in saturated mode. The PIN diode type of diode that has three layers contrary to other diodes. In circuit diagrams, a diode is represented by a triangle with a line across one vertex..
