CASE 318, STYLE 12
SOT23 (TO236AB)
These Schottky barrier diodes are designed for high speed switch-
ing 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) @ I
