SDB310WKUF
SCHOTTKY BARRIER DIODE
General Purpose Schottky Barrier Diode
General Description
These Schottky barrier diodes are designed for high-speed
switching applications, circuit protection, and voltage clamping.
Extremely low forward voltage reduces conductions. Miniature
surface mount package is excellent for hand-held and portable
applications where space is limited.
