Key Difference: A diode is a type of electrical device that allows current to move through it in only one direction. It consists of an N-type semiconductor and a P-type semiconductor that are placed together. A capacitor consists of two conductors which are separated by a dielectric medium. It stores electrical charge and is capable of discharging it whenever required. A diode is a lossy passive electronic component, whereas a capacitor is a non-lossy passive electronic component.
A diode is a type of electrical device that conducts the current only in one direction. The direction is defined from anode to cathode. In other words, it is the simplest of the two terminal unilateral semiconductor devices. It permits the current to flow in one direction and at the same time it also blocks the current that flows from the opposite direction. The two terminals of the diodes are known as anode and cathode. A diode can be closely related to a switch. Mainly there are two types of semiconductor diodes –
A P-N junction diode - which forms an electrical barrier at the interface between N and P type of semiconductor layers
A Schottky diode - a semiconductor metal junction is formed between a semiconductor and a metal, thus creating a Schottky barrier

Diodes are often used for rectifying an Alternating Current voltage to a Direct Current voltage. There are various types of diodes.

A capacitor is an electronic component that stores energy in the form of an electric field. It is constructed by using closely spaced conductors. In functioning, it acts quite similar to small rechargeable batteries. Therefore, it is able to store and release electrical energy.
