For general purpose applications
The LL103 series is a Metal-on-silicon junction 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. Other applications are click suppressions, efficient full wave
bridges in telephone subsets, and blocking diodes in rechargeable low
voltage battery systems.
These diodes are also available in the DO-35 case with the type
SD103A to SD103C ,in the SOD-123 case with the type
to SD103CWand in the SOD-323 case with type
