DESCRIPTION

Single chip Schottky rectifiers suited to Switched

Mode Power Supplies and high frequency DC to

DC converters.

Packaged in SMA and SMB, this device is

especially intended for surface mounting and used

in low voltage, high frequency inverters, free

wheeling and polarity protection applications.
