1N58xx Schottky diodes

The 1N58xx is a series of medium power, fast, low voltage Schottky diodes, which consists of part numbers 1N5817 through 1N5825.^[2][3][4]

A schematic symbol for Schottky diodes

1N5822 Schottky diode with cut-open packaging. The semiconductor in the center makes a Schottky barrier against one metal electrode (providing rectifying action) and an ohmic contact with the other electrode.

Overview

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 current (approximately 1 mA at room temperature and increasing with temperature).

Common surface-mount relatives of the 1N58xx series are the SS1x and SS3x series, such as the SS14 (1 ampere) and SS34 (3 ampere) surface-mount parts.^[1][5]
