SD103B

SD103A THRU SD103C Schottky Diodes DO-35 min. 1.083 (27.5) FEATURES ♦ For general purpose applications. ♦ The SD103 series is a metal-on-silicon max. ∅.079 (2.0) Cathode Mark min. 1.083 (27.5) 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. max. .150 (3.8) max. ∅.020 (0.52) ♦ This diode is also available in MiniMELF case with the type designation LL103A … LL103C and SOD-123 case with the type designations SD103AW .. SD103CW.
