FEATURES
For general purpose applications
MiniMELF
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
0.063(1.6)
0.055(1.4)
rechargeable low voltage battery systems.
These diodes are also available in the DO-35 case with the type designation
SD103A to SD103C.
