Overview
The MBRS190T3 Schottky Rectifier, produced by onsemi, employs the Schottky Barrier principle in a large area metal-to-silicon power diode. This device features 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 to the system.
