Product Description

Product Overview

The SK52B THRU SK510B series are surface mount Schottky barrier rectifiers designed for efficient power rectification. These devices feature a metal silicon junction for majority carrier conduction, resulting in low power loss and high efficiency. They are ideal for automated placement due to built-in strain relief and offer high forward surge current capability. Applications include general rectification where high efficiency and low power loss are critical.
