| LESHAN RADIO COMPANY, LTD. Dual Series 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 BAT54SWT1 30 VOLTS DUAL SERIES SCHOTTKY AND BARRIER DIODES 3 1 2 CASE 419, STYLE 9 SOT-323 (SC-70) ORDERING INFORMATION Device BAT54SWT1 Package SOT-323 Shipping 3000/Tape & Reel ANODE 1 3 CATHODE 2 Preferred: devices are recommended choices for future use and best overall value.
