LRC BAT54HT1 Datasheet
Schottky Barrier Diodes
LESHAN RADIO COMPANY, LTD.
BAT54HT1
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
