SD103A thru SD103C
Small-Signal Diode
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, steering, 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 recharge-
able low voltage battery systems.
These diodes are also available in the MiniMELF case with type
designations LL103A thru LL103C.
