LESHAN RADIO COMPANY, LTD. Dual Series Schottky LBAT54SWT1 Barrier Diodes 30 VOLTS DUAL SERIES SCHOTTKY AND BARRIER These Schottky barrier diodes are designed for high speed switching applications, circuit protection, and voltage clamping. Extremely low forward DIODES voltage reduces conduction loss. Miniature surface mount package is excellent for hand held and portable applications where space is limited. • Extremely Fast Switching Speed 3 • Low Forward Voltage — 0.35 Volts (Typ) @ I F = 10 mAdc 1 2 SOT–323 (SC–70) ORDERING INFORMATION Device Package LBAT54SWT1 SOT–323 CATHODE ANODE 1 2 Shipping 3000/Tape & Reel 3 CATHODE/ANODE Preferred: devices are recommended choices for future use and best overall value.
