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.
