| WSD751D Surface Mount Schottky Barrier Diodes P b Lead(Pb)-Free * Halogen Free * Slicon Epitaxial Planer * Low Forward Voltage and Low Reverse Current * High Reliability * Schottky Barrier Diodes Encapsulated in a SOD-923 Package Feature: SMALL SIGNAL SCHOTTKY DIODES 30m AMPERES 40 VOLTS 1 2 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.
