Schottky Barrier Diode
Lead free product
Halogen-free type
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.

Notes: 1. A 2.0k variable resistor adjusted for a Forward Current (IF) of 10mA.
2. Input pulse is adjusted so IR(peak) is equal to 10mA.
