NH SR340 DO15 Schottky Rectifier with Metal Silicon Junction and High Frequency Operation Capability
Product Overview
The SR320 thru SR3200 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 offer low power loss with high efficiency. They are designed for high current capability with ultra-low forward voltage drop and high surge capability, suitable for low voltage, high frequency inverters, DC/DC converters, free wheeling, and polarity protection applications.
