Product Description

Product Overview

The DSP8-08A is a standard 3-phase leg rectifier from Littelfuse, featuring planar passivated chips for very low leakage current and forward voltage drop. Its improved thermal behavior makes it suitable for main rectification in both single and three-phase bridge configurations. The device comes in an industry-standard TO-220 package and is RoHS compliant.
