 WSD520G/521G
Surface Mount Schottky Barrier Diodes
Feature: SMALL SIGNAL SCHOTTKY DIODES 100m AMPERES 30 VOLTS
*Slicon Epitaxial Planer *Low Forward Voltage and Low Reverse Current *High Reliability *Schottky Barrier Diodes Encapsulated in a SOD-723 Package
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.
