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