Working Principle

The 1N5415US is a single rectifier diode. It is designed to rectify alternating current (AC) into direct current (DC). The device works by allowing current to flow in one direction, while blocking current in the opposite direction. This directionality is achieved by a phenomenon called the “diode effect”, which is the tendency of oppositely charged carriers to flow in different directions in a semiconductor material.

In a single rectifier diode such as the 1N5415US, the opposite directions of current flow are defined by the anode and cathode terminals. The anode is the positive terminal, and the cathode is the negative terminal. When the anode voltage is positive, current will flow from anode to cathode. In this forward-biased state, the device drops a small voltage of about 1.4 V due to the diode effect.

The 1N5415US can also be used in blocking and freewheeling applications. In a blocking application, the diode is used to block current from flowing in reverse. In a freewheeling application, the diode is used to provide current path while allowing the current source to disconnect, aiding in the reduction of generated heat.
