LL101A...LL101C SILICON SCHOTTKY BARRIER DIODES for general purpose applications The LL101 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. This diode is also available in DO-35 case with type designation SD101A, B, C.
