Full Plastic Dual Schottky Barrier Power Rectifiers

SRF2070CE Thru SRF20100CE

SCHOTTKY BARRIER

RECTIFIERS

Using the Schottky Barrier principle with a Molybdenum barrier metal. 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.
