ETL BAT54RALT1

Schottky Barrier Diodes
BAT54RALT1
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) @ I F = 10 mAdc
