VOLTAGE RANGE:
70V
POWER DISSIPATION:
400 mW
SMALL SIGNAL SCHOTTKY DIODES
For general purpos e applications
Metal s ilicon s chottky barrier device which is protected
by a PN junction guard ring. The low forward voltage
drop and fas t s witching m ake it ideal for protection of
MOS devices ,s teering,bias ing and coupling diodes for
fas t s witching and low logic level applications
