FEATURES
Extremely High Switching Speed
Low Forward Voltage and Low Reverse Current
High Reliability.
Schottky Barrier Diodes Encapsulated
in a SOD-523 Package
DESCRIPTION
These schottky barrier diodes are designed for high
speed Switching applications circuit protection, and
voltage clamping, Extremely low forward voltage
reduces conduction loss, Miniature surface mount
package is excellent for hand held and Portable
applications where space is limited
