30 VOLTS SCHOTTKY BARRIER DETECTOR AND SWITCHING DIODE
Schottky Barrier Diode
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) @ IF=10mAdc
