Overview
The MBRM120ET3 is a surface mount Schottky power rectifier produced by onsemi. This device employs the Schottky Barrier principle with a barrier metal and epitaxial construction, offering optimal forward voltage drop and reverse current tradeoff. The POWERMITE package provides a highly efficient, micro miniature, and space-saving design, making it ideal for use in portable and battery-powered products. Despite being discontinued for new designs, it remains a significant component in existing applications due to its performance and compact size.
