Overview
The MBRS140T3 is a surface mount Schottky power rectifier produced by onsemi. This device employs the Schottky Barrier principle in a large area metal-to-silicon power diode, featuring state-of-the-art geometry with epitaxial construction, oxide passivation, and metal overlay contact. It is ideally suited for low voltage, high frequency rectification, or as free wheeling and polarity protection diodes in surface mount applications where compact size and weight are critical.
