Preferred Device
Dual Series
Schottky Barrier Diode
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.
Features
•Extremely Fast Switching Speed
•Low Forward Voltage
•Pb-Free Package is Available
