SD101A

SD101A - SD101C FEATURES : • 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. • These diodes are also available in the MiniMELF case with type designations LL101A thru LL101C. • Pb / RoHS Free SCHOTTKY BARRIER DIODES DO - 35 Glass (DO-204AH) 0.079(2.0 )max. 1.00 (25.4) min.
