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 2.0 k
variable resistor adjusted for a Forward Current (I
F
) of 10mA.
Notes:
2. Input pulse is adjusted so I
R(peak)
is equal to 10mA.
