 PAK SURFACE MOUNT POWER PACKAGE 
The D
2 
PAK Power rectifier employs 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.
