Schottky Barrier Diodes
LBAT54WT1
30 VOLTS SCHOTTKY BARRIER
DETECTOR AND SWITCHING
These Schottky barrier diodes are designed for high speed
switching applications, circuit protection, and voltage clamping.
DIODES
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
