SCHOTTKY BARRIER RECTIFIER
Schottky Power Rectifier
Surface Mount Power Package
Employs the Schottky Barrier principle in a large area
metal-to-silicon power diode. State-of-the-art geometry
features epitaxial construction with oxide passivation
and metal overlay contact. Ideally suited for low voltage,
high frequency rectification, or as free wheeling and
polarity protection diodes, in surface mount applications
where compact size and weight are critical to the
system.
FEATURES :
* Very Low Forward Voltage Drop
* Small Compact Surface Mountable Package
* Highly Stable Oxide Passivated Junction
* Guardring for Stress Protection
* Pb / RoHS Free
