SD103A, SD103B, SD103C
Vishay Semiconductors
Small Signal Schottky Diodes
Features
• 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.
• These diodes are also available in the SOD-123
and SOD-323 case with type designations
SD103AW(S)-V...SD103CW(S)-V, and in the
MiniMELF case with type designations LL103A
thru LL103C.
• For general purpose applications
• AEC-Q101 qualified
