UES805

Diodes - Rectifiers - Single

The UES805 is a single-phase rectifier diode package with a maximum voltage of 800 volts, and a forward current of 8 A. The diode consists of one PN junction, which block the current flow in one direction. The structure of the UES805 provides a fast switching speed, meaning it can handle large current pulses.

Basic Working Principle

The basic working principle of a UES805 is rectification, which converts AC (alternating current) to DC (direct current). The diode works by allowing current to flow in one direction, while blocking current from flowing in the opposite direction. The diode’s rectification capability depends on the internal structure of its PN junction.

When a voltage is applied, the electrons move to the positive side of the PN junction, allowing current to flow in one direction. When the voltage is reversed, the PN junction rolls over, preventing current from flowing in the opposite direction. The speed at which electrons can move, and the way the PN junction rolls over, is determined by the structure of the diode.

Applications

The UES805 is designed for applications where high current rectification is needed. Due to its fast response time and high current rating, it’s often used in switch mode power supplies, DC switching circuits, automotive start/stop systems, AC power supplies and other power regulation systems.

The UES805 is also ideal for battery charging systems such as lithium-ion or NiMH, as it can draw up to 8 A of current with minimal power loss. It can also be used in solar panel systems, as the diode has a low forward voltage drop and can handle large current pulses.

Advantages

The UES805 has several advantages over other rectifier diodes. Its fast switching time means that it can handle large current pulses, while its low forward voltage drop helps to reduce power loss during conversion. The diode can also handle high surge currents, making it suitable for applications where large current spikes are expected. The UES805 is also capable of operating at high temperatures, making it suitable for a wide range of applications.
