Description
MBRS140T3 is a Schottky barrier rectifier diode used in surface-mount power circuits. It is rated for about 1 A average forward current and 40 V reverse voltage. The device provides a very low forward voltage drop (roughly 0.4–0.5 V at 1 A) and ultrafast switching, which reduces conduction and switching losses in switching regulators. Typical applications include DC–DC converters (buck/boost), freewheeling/rectification in power supplies, OR-ing diodes, and reverse-polarity protection. It comes in a compact surface-mount package with a cathode stripe to indicate polarity.
