DGS20-018A

Diodes - Rectifiers - SingleThe DGS20-018A is a single-phase silicon rectifier used in power applications such as DC power supply, freewheeling diodes, bridge rectifiers, and synchronous rectification. It is a high voltage silicon prostaglandin rectifier with a breakdown voltage of 400V and a maximum forward surge current of 15A. In addition, it has a forward voltage drop of 2.6V, making it an excellent choice for applications such as power supplies and motor drives.Application Field:The DGS20-018A has a wide range of potential applications in the field of power electronics. It is an ideal candidate for bridge or freewheeling diodes, single-phase rectification, power supply design, power controllers, motor drives, and synchronous rectification. It can be used in circuits with high input voltage and high current applications.Working Principle:The working principle of the DGS20-018A is based on the flow of current from an external supply to the diode. When the external voltage is higher than the voltage across the diode, the diode will forward bias and current will flow from the external source to the diode. This process is known as forward conduction. On the other hand, when the external voltage is lower than the voltage across the diode, the diode will reverse bias and current will not flow through the diode. This process is known as reverse conduction or blocking.The DGS20-018A has a maximum reverse voltage rating of 400V, meaning the diode will withstand 400V applied to the anode without conducting current. It also has a maximum forward current rating of 15A. This means the diode can safely conduct up to 15A of current without suffering damage due to heating.In power applications, the DGS20-018A is used to rectify alternating electrical current into direct electrical current. This is accomplished by connecting the diode to the Secondary of a transformer with the cathode of the diode connected to ground. Alternating current from the transformer is applied to the anode, and since the secondary of the transformer has alternating polarity, the diode alternately forward biases and reverse biases. Alternating current will be rectified to direct current as the diode passes current on the forward bias cycles and blocks current on the reverse bias cycles.The DGS20-018A can also be used in a full-wave rectifier configuration. This is done by connecting two DGS20-018A diodes in a bridge configuration with the anodes of both diodes connected to the transformer secondary and the cathodes connected to ground. This will allow for both the positive and negative cycles of the alternating current to pass through the diodes and be rectified to direct current.The DGS20-018A is an ideal choice for a wide range of power applications and is capable of withstanding a high voltage and current rating, making it more suited to higher power applications. It has a low forward voltage drop and low dynamic impedance, making it ideal for high efficiency rectification in higher power systems.
