  • Description

    The Sanrex DF30AA120 is a single-phase bridge rectifier diode module rated for 30 amperes and a peak repetitive reverse voltage of 1200V. Built to Sanrex's proven DF-series standards, this module integrates four diodes in a full-wave bridge configuration within a single isolated package, simplifying thermal management and reducing overall system component count. The isolated baseplate design enables direct mounting to a heatsink without additional insulation hardware, making it a preferred choice for engineers designing compact, thermally efficient power stages.

    The DF30AA120 is well-suited for a wide range of industrial and commercial power conversion applications including AC drive front-end rectification, UPS systems, welding equipment, battery chargers, DC power supplies, and soft-starter circuits. Its 1200V voltage rating provides generous margin in 480VAC three-phase systems after accounting for line transients, while the 30A current rating covers a broad segment of medium-power drive and converter designs.
