LESHAN RADIO COMPANY, LTD. Schottky Barrier Diodes These Schottky barrier diodes are designed for high speed switching applications, circuit protection, and voltage clamping. Extremely LBAT54ALT1 low forward voltage reduces conduction loss. Miniature surface mount package is excellent for hand held and portable applications where space is limited. 30 VOLTS SCHOTTKY BARRIER DETECTOR AND SWITCHING DIODES • Extremely Fast Switching Speed • Low Forward Voltage — 0.35 Volts (Typ) @ I F = 10 mAdc 3 Features • Pb−Free Package May be Available.
