MOSPEC S20C70 Thru S20C100 Schottky Barrier Power Rectifiers 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. 20 AMPERES 70-100 VOLTS Features Low Forward Voltage. Low Switching noise. High Current Capacity Guarantee Reverse Avalanche. Guard-Ring for Stress Protection. Low Power Loss & High efficiency. 150 Operating Junction Temperature Low Stored Charge Majority Carrier Conduction.
