MOSPEC
SRF2030 thru SRF2060
Switchmode
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.
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.
Plastic Material used Carries Underwriters Laboratory
Flammability Classification 94V-O
