SOD-723 Outline Dimensions
*Slicon Epitaxial Planer
*Low Forward Voltage and Low Reverse Current
*High Reliability
*Schottky Barrier Diodes Encapsulated in a SOD-723 Package
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.
