Diodes - Rectifiers - Single

The SD103B-TR is a device used in several applications and can be classified into the rectifiers - single diodes category. This device has been designed to deliver improved performance and lower power loss compared to regular rectifiers. It is a small and compact diode suitable for applications where size and weight requirements are important.The most common application of the SD103B-TR is as an input rectifier for DC to DC converters, such as buck converters. It can also be used as a rectifier for high frequency circuits, switching power supplies, and DC to AC converters. Additionally, the device can be used as a polarity protector, spike and surge suppressor, and in various power line transient protection circuits.The SD103B-TR is designed to provide low forward voltage drop and low leakage current. It can be operated at low forward current density, up to the rated current, with a low temperature coefficient. The device can also handle high in-rush current and reverse voltage. The working principle of the SD103B-TR is based on p-n junction. When used as an input rectifier, the SD103B-TR will allow current to flow through the diode when the voltage applied across the diode reaches a certain value which depends on the breakdown voltage of the diode. Above this breakdown voltage, current will be conducted due to the forward bias of the p-n junction.For instance, when used as an input rectifier of a DC to DC converter, the SD103B-TR will allow current to flow through the diode when the input voltage reaches the device’s breakdown voltage. The current will then be regulated by the buck converter’s inductor and the output voltage is obtained across the DC to DC converter’s output terminals. The SD103B-TR is a small and compact diode typically used as an input rectifier for DC to DC converter applications, high frequency circuits, and switch mode power supplies. It is designed to provide low forward voltage drop, low leakage current and good high in-rush current capability. Its working principle is based on p-n junction and it allows current to flow through it when the input voltage reaches its breakdown voltage.
