Surface Mount
Schottky Power Rectifier
SMA Power Surface Mount Package
. . . employing the Schottky Barrier principle in a large area metaltosilicon
power diode. 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 diodes in surface mount
applications where compact size and weight are critical to the system.
