U4A-E3/73 Application Field and Working Principle

The U4A-E3/73 diode is a single rectifier diode that is popularly used in power supplies and voltage regulation applications. It features a small form factor, low temperature coefficient, and a high power factor from a high-frequency switch-mode power supply. It is also characterized by its small junction capacitance, very low reverse leakage current, and very fast switching speed. The U4A-E3/73 rectifier provides excellent thermal and electrical performance for both AC and DC safe use, and it can be used for high-frequency applications when operated at higher temperatures (up to 350 °C).

Application Field

The U4A-E3/73 diode is used in a wide range of applications, such as high-frequency telecom applications and power supplies. Its capability of operating at higher temperatures and its very high current support allows it to be used in high-power and high-performance power supplies. It is also very common to be used in switching power supplies, voltage regulators, and motor controllers. Its low temperature coefficient, low leakage current, and low junction capacitance provide high efficiency and power factor.

Working Principle

The U4A-E3/73 rectifier works in a very simple way. The anode side of the diode is connected to its positive voltage source, and the cathode side of the diode is connected to the circuit load. When a reverse voltage is applied to the diode, the diodes cannot conduct the electric current across the load, thus it acts as an open circuit. However, when a forward voltage is applied to the diode, the diode conducts current across the load, thus allowing the flow of electric current across the load. The U4A-E3/73 rectifier can also be used to produce AC signal if the applied reverse voltage is of specified frequency.
