Product Description

Product Overview

The U1A thru U1M series are Surface Mount Ultrafast Rectifiers from Niu Hang Specification Electronic Co. Ltd. These rectifiers are designed for low voltage, high frequency applications including inverters, DC/DC converters, LED drivers, free-wheeling, and polarity protection. They feature a glass-passivated junction chip, low reverse leakage, and high forward surge current capability. The plastic package carries an Underwriters Laboratory Flammability Classification 94V-0 rating.
