Schottky diodes are often made of metal-semiconductor (M-S) contact characteristics, and there are two die structures: point contact type and surface combination type. Usually, this diode has the advantages of high switching frequency, low forward voltage, short reverse recovery time, strong surge current tolerance and high temperature resistance, and can be used in RF signal rectification and low voltage reference circuits. In this issue, Hottech recommends a Schottky diode SD103AWS, which can be used in communication power supply, smart plug and lighting.

Schottky diode SD103AWS has good electrical characteristics. It can withstand the maximum DC reverse voltage of 40V, forward current of 0.35A, direct voltage of 0.37V, reverse current of 5A, forward surge current of 2A and dissipation power of 0.4W. SD103AWS diode has low direct voltage, fast switching, low capacitance and PN junction protection ring for transient and ESD protection. The weight of the whole machine is very light, about 0.005 g, which is suitable for more lightweight circuit application scenarios.

The SD103AWS of Hottech has a high reverse withstand voltage of 40V. When the reverse voltage does not exceed 40V, the diode can remain off, effectively preventing the reverse current from passing through and achieving the purpose of protecting the circuit safety. SD103AWS has a high average rectifying current capacity, with a forward current of 0.35A The diode can handle a large current load. The diode has a lower voltage drop when it is turned on in the forward direction, which is helpful to reduce energy loss and improve efficiency. The reverse recovery time is very short, which is helpful to reduce switching loss and improve the overall performance of the circuit in high frequency applications. SD103AWS has high surge current capability and can withstand large surge current, which makes it more reliable in applications that need to deal with instantaneous large current.

SD103AWS products produced by Hottech adopt very miniaturized SOD-323 packaging form, which has the characteristics of very fast reaction speed, high-density installation, low turn-on voltage, small volume, light weight and excellent heat dissipation, and is very suitable for the design of circuits that need miniaturization. This packaging form not only helps to save circuit board space, but also is suitable for application scenarios that require high space.

It is the SD103AWS product that has the above characteristics, and it has been widely used in communication power supply, frequency converter, smart plug, intelligent lighting, high-frequency switch and other scenes. The main function of SD103AWS is rectification and switching. Taking the frequency converter as an example, SD103AWS is used in the rectification part, converting alternating current into direct current, and then converting it into alternating current with variable frequency through the inverter part, so as to realize the speed control of the motor.

Because of its low forward voltage drop and fast response, SD103AWS is very suitable for converting AC signals into DC signals. In power supply circuits, frequency converters, and other occasions, SD103AWS can effectively convert AC signals into DC signals, providing a stable DC power supply for subsequent circuits. In high-frequency circuits, SD103AWS has a fast reverse recovery time and low cut-off voltage, which makes it perform well in high-frequency applications. In high-frequency rectifiers, high-frequency switching power supplies, and other occasions, SD103AWS can quickly respond to changes in circuits, reduce switching losses, and improve the overall efficiency of circuits. SD103AWS can also be used as a high-frequency small signal amplifier, because its carrier moves faster, which is suitable for amplifying high-frequency signals and has many applications in radar transceiver systems, solar panels, and other fields. At present, the SD103AWS Schottky diode warehouse of Hottech is available. Welcome to contact Hottech customer service.
