LRC LBAT54WT1G Schottky barrier diodes extremely fast switching speed Datasheet

LESHAN RADIO COMPANY, LTD.
Schottky 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
