BAT54WT1

LESHAN RADIO COMPANY, LTD. Schottky Barrier Diodes BAT54WT1 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 30 VOLTS SCHOTTKY BARRIER DETECTOR AND SWITCHING DIODES 3 1 2 CASE 419, STYLE 2 SOT–323 (SC–70) ORDERING INFORMATION Device BAT54WT1 Package SOT–323 Shipping 3000/Tape & Reel 3 CATHODE 1 ANODE Preferred: devices are recommended choices for future use and best overall value.
