RB751V40T1

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

• Extremely Low Forward Voltage – 0.28 Volts (Typ) @ I

• Low Reverse Current
