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 — 0.35 Volts (Typ) @ IF = 10 mAdc
