LL103A-LL103C
Small Signal Schottky Diodes
Features
For general purpose applications
Metal silicon schottky barrier device which is protected
by a PN junction guard ring. The low forward voltage
drop and fast switching make it ideal for protection of
MOS devices,steering,biasing and coupling diodes for
fast switching and low logic level applications
