SCHOTTKY POWER RECTIFIER
DISCRETE POWER AND SIGNAL
TECHNOLOGIES
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.
Absolute Maximum Ratings* TA = 25
Features:
• Compact surface mount package with J-bend leads (SMC).
• 3.0 Watt Power Dissipation package.
• 3.0 Ampere, forward voltage less than 525 mv
Ordering:
• 13 inch reel (330 mm); 16 mm Tape; 3,000 units per reel.
