The SK32 thru SK310 series are surface mount Schottky barrier rectifiers designed for applications requiring low power loss and high efficiency. Featuring a metal silicon junction with majority carrier conduction, these rectifiers offer built-in strain relief, making them ideal for automated placement. They provide high forward surge current capability and are guaranteed for high-temperature soldering. Typical applications include power supplies, inverters, and general rectification where high performance and reliability are essential.
