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 rechargeable low voltage battery systems. These diodes are also available in the MiniMELF case with type designations LL103A thru LL103C.
