Product Description

Product Overview

The DSI45-12A is a single diode standard rectifier featuring planar passivated chips for very low leakage current and a low forward voltage drop. It offers improved thermal behavior and is designed for main rectification in single and three-phase bridge configurations. The device comes in a RoHS-compliant TO-247 package, an industry-standard outline with epoxy meeting UL 94V-0 flammability standards.
