Schottky Barrier Diodes
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.

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits
are exceeded, device functional operation is not implied, damage may occur
and reliability may be affected.
