GALAXY ELECTRICAL LL103B
BL GALAXY ELECTRICAL
SMALL SIGNAL SCHOTTKY DIODE
LL103A---LL103C
VOLTAGE RANGE: 40 -- 20 V
CURRENT: 400 mW
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
