Description
Single chip Schottky rectifiers suited to Switched
Mode Power Supplies and high frequency DC to
DC converters.
Packaged in SMB, and low profile SMB, this
device is especially intended for surface mounting
and used in low voltage, high frequency inverters,
free wheeling and polarity protection applications.
