The electronic components of the 1N4002E-E3/54 single rectifier diode include an Anode and Cathode connection, which are the two terminals of the 1N4002E-E3/54. The Anode is the positive (+) terminal of the diode, while the Cathode is the negative (-) terminal. A reverse bias applied between these two terminals can cause current flow in the opposite direction. While a forward bias applied between these two terminals makes it easier for current to flow.

The working principle of the 1N4002E-E3/54 single rectifier diode is based on the property of p-n junction. The p-n junction of the diode is essentially two layers of semiconductor material, one positive and one negatively charged, which create an electric field in the space between them. When a bias voltage is applied to the diode, electrons and holes flow in the opposite direction. When the bias voltage reaches a specific point, the electric field is strong enough to prevent the flow of electrons, resulting in the blocked current flow.
