Schottky Barrier Diode
30 VOLTS SCHOTTKY BARRIER DETECTOR AND SWITCHING 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.
