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.
Low Forward Voltage.
Low Switching noise.
High Current Capacity
Guarantee Reverse Avalanche.
Guard-Ring for Stress Protection.
Low Power Loss & High efficiency.
125Operating Junction Temperature
Low Stored Charge Majority Carrier Conduction.
Plastic Material used Carries Underwriters Laboratory
