Schottky Diodes
Features
DO-204AH (DO-35 Glass)
Dimensions in inches
and (millimeters)
• 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.
• These diodes are also available in the SOD-123
case with type designations SD103AW...SD103CW
and in the MiniMELF case with type designations
LL103A thru LL103C.
