SD103A - SD103C SCHOTTKY BARRIER DIODES
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.
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
