IntroductionCDBUR43 is a diode rectifier in the form of a single package. It has been developed to provide a reliable and robust way of rectifying current and consequently providing DC power from AC power sources. CDBUR43 is a double sided, three-terminal, stud mounted diode rectifier and is designed to operate in power supplies. Application FieldCDBUR43 is used in a wide range of applications. These include switching power supplies, output stages in amplifiers, DC/DC converters, voltage regulators and in production, measurement, and control automation. CDBUR43 is extremely effective in laptop and desktop computers, computer motherboards and other power densities up to 10A continuous load current. It can also be used in all typical switching and linear power supplies, as well as high power LED drivers and point-of-load converters. CDBUR43 is suitable for applications that require a high degree of insulation or high voltage operation, and its wide common mode transient immunity range up to ±60V. Furthermore, with its large input and output offset range, it is suitable for all voltage regulators and DC to DC converters. Working PrincipleThe working principle of CDBUR43 is quite simple. When current passes through it, the diode rectifies the current from AC to DC. This rectified current is then used in a variety of applications, depending on the specific application.The working principle of CDBUR43 is based on the PN junction, which is the characteristic of any diode rectifier. When an AC current passes through it, only one direction of the current passes, while the other direction is restricted or blocked. The rectified DC current will oscillate at the same frequency of the AC current, but the amplitude will be regulated and limited due to the characteristic of the diode. The diode’s junction allows the reverse current to pass through it at a certain limited voltage. When this voltage exceeds the breakdown voltage of the diode, the diode starts conducting in the reverse direction and the diode rectification occurs in both directions. Due to the surge current and the high junction temperature of the device, the gold wire bonds and ceramic housing of CDBUR43 are designed to withstand the power dissipation in the application. ConclusionCDBUR43 is a diode rectifier in the form of single package. It is designed for use in power supplies, laptop and desktop computers, amplifiers, DC/DC converters and in many other applications. The working principle of CDBUR43 is based on the PN junction, which is the characteristic of any diode rectifier. The diode rectifies the AC current to DC current and it is used in a wide range of applications. Moreover, due to its high insulation property and wide common mode transient immunity range, it is suitable for all voltage regulators and DC to DC converters.
