Product Description

Product Overview

The US1A thru US1M series are 1.0 Amp Ultra Fast Recovery Silicon Rectifiers designed for low power loss and high efficiency. They are ideally suited for automatic assembly and feature a guard ring die construction. The plastic case material has a UL Flammability Classification Rating of 94V-0. These rectifiers are designed for single phase, half-wave rectification with a 60Hz frequency and can be used with resistive or inductive loads. For capacitive loads, the current should be derated by 20%. The polarity is indicated by a color band denoting the cathode end.
