LRC BAT54SWT1 Datasheet
Dual Series Schottky
LESHAN RADIO COMPANY, LTD.
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 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
