SD103AWS THRU SD103CWS
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
rechargeable low voltage battery systems.
This diode is also available in Mini-MELF case with the
type designation LL103A ... LL103C, DO-35 case with
the type designations SD103A .. SD103C and SOD-123
case with type designations SD103W ... SD103CW.
