SCHOTTKY POWER RECTIFIER

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 (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.
