MAIN PRODUCT CHARACTERISTICS

VERY SMALL CONDUCTION LOSSES

NEGLIGIBLE SWITCHING LOSSES

LOW FORWARD VOLTAGE DROP

SURFACE MOUNTED DEVICE

FEATURES AND BENEFITS

Single chip Schottky rectifier suited for Switch-

mode Power Supplies and high frequency DC to

DC converters.

Packaged in SMA and SMB(*), this device is in-

tended for surface mounting and used in low volt-

age, high frequency inverters, free wheeling and

polarity protection applications.
