DS75-08B

DS75-08B Application Field and Working Principle

The DS75-08B is a high current Schottky rectifier diode, which belongs to the diode’s rectifier single type. It has a VRRM (Rated repetitive peak reverse voltage) of 75V and an IF (Average forward current) of 18A. The two major application fields of the DS75-08B are power supplies and switching power converters. As for the working principle, it basically consists of two same transistors connected together in opposite directions, forming a PN junction, which allows electric current to flow only in one direction.

Application Fields

The DS75-08B is mainly used in power supplies and switching power converters. In power supplies, the DS75-08B can be used to convert AC to DC by allowing only positive current to pass through it, thus regulating the amount of current fed to the device. When used in a switching power converter, the DS75-08B can be used to condition an alternating current by limiting it to a direct current, which can then be used to power an electrical device or a circuit. The DS75-08B can also be used in low voltage halogen lamp illumination systems.

Construction

The main element of the DS75-08B is the PN junction diode, which is constructed with two same transistors connected in opposite directions. The PN junction is formed when P-type semiconductor material is joined to N-type semiconductor material, which allows electric current to flow only in one direction. The direction of the current is determined by the type of semiconductor on each end of the PN junction. The PN junction has a high resistance value when the direct current flows in the opposite direction.

Operation

The DS75-08B functions by using the rectifying property of the PN junction. When a direct current is applied to the PN junction, the electrons in the N-type material flow through the junction and into the P-type material, creating a voltage drop (known as the “forward biased”). This forward biased allows current to flow in only one direction, allowing for the conversion of alternating current to direct current.

Features

The main features of the DS75-08B are its rated repetitive peak reverse voltage (VRRM) of 75V and its average forward current (IF) of 18A. The DS75-08B also has a fast switching speed, low forward voltage drop (VF), and a high breakdown voltage (BV). The DS75-08B can also withstand up to 200A surge current, making it an ideal choice for applications that require high current or high voltage.
