Small Signal Schottky Diodes
VOLTAGE RANGE: 15 V
CURRENT: 30 mA
DO - 35(GLASS)
Features
For general purpose applications
Metal silicon schottkybarrier device which is protected
bya 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
