SD103B

SD103A - SD103C 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. • Pb / RoHS Free SCHOTTKY BARRIER DIODES DO - 35 Glass (DO-204AH) 0.079(2.0 )max. 1.00 (25.4) min.
