Overview
The MBRS140LT3G is a surface mount Schottky power rectifier produced by onsemi. This component utilizes the Schottky Barrier principle in a large area metal-to-silicon power diode, making it ideal for low voltage, high frequency rectification. It is also suitable for use as free-wheeling and polarity protection diodes in surface mount applications where compact size and weight are critical.
