Description/ Features
This Schottky barrier diode is designed for high speed
switching application, voltage clamping and circuit protection.
Miniature surface mount packages with reduced footprint are
excellent for portable application where space is limited.
Small footprint, surface mountable
Very low forward voltage drop
Extremely fast switching speed for high frequency operation
