The 1N2138AR belongs to the category of diodes, rectifiers, single and is a medium-power rectifier that is designed to bridge changes in the direction of current flow. It is designed to bridge related electrical changes between two electrodes in an alternating current (AC) system. It is composed of two semiconductor layers that are connected with an anode and a cathode. In DC systems, rectifiers are devices which turn AC (electromotive force) into DC (direct current). The 1N2138AR has a medium-power capacity with a maximum current of 1.0A and a maximum forward voltage drop of 1.2V at f=60Hz. It is commonly used in the production of switching power supplies, consumer electronics, AC-DC converters and automotive electronics. The working principle of the rectifier is based on its ability to conduct current in only one direction and act as an insulator when the current is in the opposite direction. It is primarily composed of two diodes that have opposite polarities which are connected to the anode and cathode. When the circuit is closed, the current will always take the path of least resistance which is provided by the diodes. When an alternating current is applied to the rectifier, the current will flow through the anode and cathode path and the rectifier will allow only one of the two current directions to pass through it. It is able to do this because it has a negative resistance, which creates a voltage drop across its terminals when current passes through, and it prevents current from passing in the opposite direction. Once the charge is transferred from both terminals, the rectifier will act as an insulator, blocking current from passing, and the diodes are then reversed. This process is then repeated again and again until the alternating current has been completely converted to a direct current. This can be demonstrated by connecting the rectifier to an AC-DC converter which will use the alternating current to produce a direct current. Overall, the 1N2138AR is a medium-power rectifier that is designed to bridge changes in direction of current flow in AC systems and is used in applications such as switching power supplies, consumer electronics, AC-DC converters and automotive electronics. It consists of two semiconductor layers that are connected with an anode and a cathode and uses a negative resistance element to convert alternating current to direct current.
