Schottky Diodes
Features
For general purpose applications.
The SD103 series is a metal-on-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, steer-
ing, biasing, and coupling diodes for fast switching
and low logic level applications.
Other applications are click suppression, efficient
full wave bridges in telephone subsets, and blocking
diodes in rechargeable low voltage battery systems.
This diode is also available in the MiniMELF case
with the type designations LL103A to LL103C,
DO-35 case with the type designations SD103A to
SD103C and SOD-323 case with type designations
SD103AWS to SD103CWS.
