BAT54SWT1
30 VOLTS DUAL SERIES
SCHOTTKY AND BARRIER
DIODES
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 excel-
lent for hand held and portable applications where space is limited.
• Extremely Fast Switching Speed
