Metal silicon junction NH SR2150 Schottky rectifier ideal for freewheeling and surge current handling
Product Overview
The SR220 thru SR2200 series are Schottky rectifiers from Niu Hang Specification Electronic Co. Ltd, designed for low voltage, high frequency applications including inverters, DC/DC converters, freewheeling, and polarity protection. These rectifiers feature a metal silicon junction with majority carrier conduction, a guard ring for overvoltage protection, low power loss, high efficiency, high current capability, ultra-low forward voltage drop, and high surge capability. They are housed in a JEDEC DO-201AD molded plastic package and are compliant with RoHS 2011/65/EU.
