Product Description
Product Overview
The SK52B THRU SK510B series are surface mount Schottky barrier rectifiers designed for efficient power rectification. These devices offer low power loss and high efficiency due to their majority carrier conduction and metal silicon junction. They are suitable for automated placement with built-in strain relief and provide high forward surge current capability. Applications include general-purpose rectification where high surge capability and efficiency are required.
