MBRF30045R Equivalent & Substitute Parts Reference

Part Overview

The GeneSiC Semiconductor MBRF30045R is a Schottky diode array configured as 1 Pair Common Anode, rated for 45 V maximum reverse voltage and 150A average rectified current per diode. The device is chassis mountable in a TO-244AB package. As the MBRF30045R is now obsolete, direct substitutes are required for continued design support and field maintenance in systems utilizing this rectifier, specifically within the Diodes, Rectifiers category.
