MS17 thru MS19

Surface Mount

Schottky Barrier rectifiers

Using the Schottky Barrier principle with a Molybdenum barrier meta.

These 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.
