The 1N5822 is a Schottky diode that is commonly used in a variety of electronic circuits. It is a type of rectifier diode that is designed to rectify alternating current (AC) into direct current (DC). The 1N5822 has a forward voltage drop of approximately 0.4V and is able to handle a maximum current of 3A. It is also rated for a maximum reverse voltage of 40V.

Schottky diodes are known for their fast switching speed and low forward voltage drop, which make them suitable for use in high-frequency circuits and in applications where power efficiency is important. They are also used to prevent voltage spikes, eliminate noise, and protect circuits from damage. The 1N5822 is often used in power supply circuits, battery chargers, and other high-current applications.

The 1N58xx is a series of medium power, fast, low voltage Schottky diodes, which consists of part number numbers 1N5817 through 1N5825

The 1N581x are typically packaged in the DO-41 axial through-hole case, and in many cases are interchangeable with the 1N4001 series. The 1N582x are typically packaged in the DO-201AD through-hole case, and in many cases are interchangeable with the 1N54xx series.

Being Schottky diodes, the 1N58xx parts have roughly half the forward voltage drop of the 1N400x/1N540x series diodes, which improves efficiency in applications where they are usually forward-biased, such as power converters. The cost is a lower voltage rating and higher reverse leakage (approximately 1 mA at room temperature and increasing with temperature).
