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. Minia-
ture surface mount package is excellent for hand held and por-
table applications where space is limited.
