LL103A - LL103C SCHOTTKY BARRIER DIODES MiniMELF (SOD-80C) FEATURES : Cathode Mark • For general purpose applications • The LL103A, B, C 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 DO-35 case with type designation SD103A, B, C • Pb / RoHS Free φ 0.063 (1.64) 0.055 (1.40) 0.019(0.48) 0.011(0.28) 0.142(3.6) 0.134(3.4) Mounting Pad Layout 0.098 (2.50) Max. 0.049 (1.25)Min. 0.079 (2.00)Min.
