Overview
The MBRM120LT1 is a surface mount Schottky power rectifier produced by onsemi. This component utilizes the Schottky Barrier principle with a barrier metal and epitaxial construction, offering an optimal forward voltage drop and reverse current tradeoff. The advanced packaging techniques of the POWERMITE® design provide a highly efficient, micro-miniature, and space-saving surface mount rectifier. It boasts the same thermal performance as the SMA package but is 50% smaller in footprint area and has one of the lowest height profiles in the industry, with a maximum height of less than 1.1 mm.
