WSD521D

WSD521D Surface Mount Schottky Barrier Diodes P b Lead(Pb)-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 100m AMPERES 30 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.
