LESHAN RADIO COMPANY, LTD. Dual Series Schottky LBAT54CLT1 Barrier Diodes 3 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 1 2 SOT-23 ANODE ANODE 1 2 3 ORDERING INFORMATION Device LBAT54CLT1 Package SOT–23 CATHODE Shipping 3000/Tape & Reel Preferred: devices are recommended choices for future use and best overall value.
