Diodes are electrical components primarily used to permit an electric current to pass in one direction while blocking it in the other. Single rectifiers are a type of diode specifically engineered to convert alternating current (AC) to direct current (DC). Rectifiers are widely used in power supplies, electrical systems, as well as telecommunication and radio receiver components. Nowadays, considerable efforts have been devoted to developing RFN20NS6SFHTLs, a type of single rectifiers, which are used for a range of applications. The following will discuss the application fields and working principles of RFN20NS6SFHTLs.

Application Field

RFN20NS6SFHTLs are triple-diffused planar silicon rectifiers, specifically designed for use in high-frequency power conversion circuits. This type of single rectifier is often used for AC and DC power supplies in which the efficiency of high frequency switching devices may be degraded in the presence of forward voltage drops at the device. Therefore, RFN20NS6SFHTLs are suitable for high-frequency operations, especially in the radio or communication circuits that require intermediate frequency response.

The normal forward current of RFN20NS6SFHTLs is 2A and its normal reverse voltage is 20V. These single rectifiers are characterized in terms of low leakage current and extremely low forward voltage drop at high temperatures. Moreover, RFN20NS6SFHTLs exhibit excellent thermal stability and high reliability, while their soft recovery features enable optimized EMI, as well as extend the life of the device. Such features make them suitable for applications in automotive ECUs, battery charger, telecom, server power supply and heater.

Working Principle

The basic principle of the RFN20NS6SFHTL single rectifier is the same as for any other diode. When the diode is forward-biased and there is an electric current flowing through the diode, the junction barrier can be easily crossed and the current will be rectified. The RFN20NS6SFHTL employs the principle of P-N junction. This helps regulate or control the current flow in one direction in response to the alternating current that is applied to the diode\'s junction terminal.

The RFN20NS6SFHTL is a triple-diffused planar silicon rectifier which makes use of three thin layers of silicon, thus improving the component\'s reliability significantly. The diode also has a low forward voltage, which enables lower losses and higher efficiency at higher frequencies. Moreover, the RFN20NS6SFHTL diode exhibits soft recovery characteristics that help avoid any electro-magnetic interferences when in use.

Overall, the single rectifier has several distinguishing features that make it ideal for use in a range of devices and applications. Its improved thermal and electrical properties along with its proven reliability make it a go-to choice for a variety of power supply and rectification jobs.
