LESHAN RADIO COMPANY, LTD. Dual Series Schottky LBAT54CWT1 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 1 package is excellent for hand held and portable applications where space is limited. • Extremely Fast Switching Speed 2 SOT-323 • Low Forward Voltage — 0.35 Volts (Typ) @ I F = 10 mAdc ANODE ANODE 1 2 3 ORDERING INFORMATION Device Package LBAT54CWT1 CATHODE Shipping SOT–323 3000/Tape & Reel Preferred: devices are recommended choices for future use and best overall value.
