Dual Series
Schottky Barrier Diode
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
• Low Forward Voltage — 0.50 Volts (Typ) @ IF = 10 mAdc
