The MBRS140T3G is a surface-mount Schottky barrier rectifier from onsemi, supplied in a 2-pin SMB package. It is rated for a 40V maximum repetitive reverse voltage (Vrrm) and 1A average rectified forward current, with a forward voltage of 600mV. Schottky rectifiers use a metal-semiconductor junction instead of a conventional P-N junction, which gives them a lower forward drop and faster switching recovery than standard silicon rectifiers. onsemi lists the MBRS140T3G at Production/Active lifecycle status, lead free and RoHS compliant, supplied on tape and reel at 2, 500 pieces per reel.

Schottky rectifiers in this voltage and current class are used for output rectification in low-voltage switch-mode power supplies, as freewheeling and catch diodes in DC-DC converter stages, and for reverse-polarity and supply OR-ing protection where the forward drop dominates efficiency. The 40V/1A rating combined with a 40A surge capability and an SMB footprint suits board-level power stages in industrial controls, computing hardware, telecom line cards and consumer equipment. Typical buyers are power-supply and embedded hardware engineers, contract manufacturers building to a fixed BOM, and sustaining-engineering teams sourcing onsemi rectifiers for existing designs.
