Surface Mount Schottky Barrier Diodes
Features: *Low Forward Voltage *Very Small Conduction Losses *Schottky Barrier Diodes Encapsulated in a SOD-123 Package
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.
