Diodes are electronic components that are used to pass current in one direction only, most commonly for converting AC (alternating current) power to DC (direct current) power. Rectifiers are used to convert AC voltage to DC voltage and are commonly found in power supplies and switch mode power supplies (SMPS). A single phase rectifier consists of a single diode and is commonly used in low power circuits, such as bridge rectifiers in power supplies. The R21140 rectifier is a single-phase, ultra-fast, soft-recovery, highly efficient, high frequency (up to 1MHz) version of the R21100 series.

The R21140 is a rectifier diode that is primarily used in power circuits. Its main application fields include AC to DC power conversion, high frequency rectification, and low-voltage circuits. The rectifier features an ultra-fast switching time that helps it convert high-frequency AC voltage to DC voltage with a high degree of accuracy and efficiency. It is ideal for use in power supplies and power conversion circuits. Its low reverse bias leakage current makes it suitable to be used in sensitive circuits, such as in noise-sensitive lighting applications. Furthermore, its high surge current capability makes it ideal for applications where high spike currents need to be handled.

The R21140 rectifier diode consists of an undoped silicon body, an anode, and a cathode. When the anode is connected to the positive line of the input AC voltage and the cathode is connected to the negative line of the input AC voltage, the diode is turned on. This causes the current to flow from the anode to the cathode in a single direction. As the current flows through the junction of the diode, the electrons are pulled from the anode to the cathode, creating a layer of negatively charged electrons which blocks the flow of current in the reverse direction. This forms the basis for the rectification process. The amount of current that is allowed to flow through the diode is determined by the forward voltage rating of the diode, which can vary from a few millivolts to nearly a hundred volts.

The R21140 rectifier diode is a highly efficient component and is capable of converting AC voltage to DC voltage without producing any wastage of energy. It is capable of switching at a high frequency of up to 1MHz, which enables it to be used in high frequency circuits. Moreover, the diode has a soft-recovery feature that ensures that no reverse current is held when the diode is turned off, thus preserving its useful life and ensuring safe operation.

Overall, the R21140 rectifier diode is a highly efficient, low voltage component that is ideal for use in low power and high frequency power conversion circuits. It features an ultra-fast switching time, high surge current capability, and low reverse bias leakage current, which makes it suitable for use in a range of DC voltage applications. Its high efficiency allows for greater energy savings in a range of electrical and electronic equipment.
