FEATURES
Low Power Rectification
Small Surface Mounting Type
Low IR (I
R
= 50nA Type)
High Reliability
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
