Product Description

Product Overview

The SR520 thru SR5200 series are Schottky Rectifiers from Niu Hang Specification Electronic Co. Ltd. These rectifiers feature a metal silicon junction with majority carrier conduction, a guard ring for overvoltage protection, and low power loss with high efficiency. They offer high current capability and ultra-low forward voltage drop, making them suitable for low voltage, high frequency inverters, DC/DC converters, free wheeling, and polarity protection applications.
