MBRS140
SCHOTTKY POWER RECTIFIER
Features:
Compact surface mount package with J-bend leads (SMB).
1.5 Watt Power Dissipation package.
1.0 Ampere, forward voltage less than 600 mv
Ordering:
13 inch reel (330 mm); 12 mm Tape; 3,000 units per reel.
General Description:
Schottky Barrier Diodes make use of the rectification effect
of a metal to silicon barrier. They are ideally suited for high
frequency rectification in switching regulators & converters.
This device offers a low forward voltage performance in a
power surface mount package in applications where size and
weight are critical.
