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.
• Extremely Fast Switching Speed
• Extremely Low Forward Voltage — 0.28 Volts (Typ) @ IF = 1 mAdc
