SD103A Datasheet, PDF (1/5 Pages) Semtech Corporation – Silicon Schottky Barrier Diodes for general purpose applications

Small Signal Schottky Diodes
SD103A/103B/103C
Vishay Semiconductors
Features
• The SD103 series is a Metal-on-silicon
Schottky barrier device which is
protected by a PN junction guard ring.
e2
• 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 block-
ing diodes in rechargeable low voltage battery sys-
tems.
• These diodes are also available in the SOD123
and SOD323 case with type designations
SD103AW(S)-V...SD103CW(S)-V, and in the
MiniMELF case with type designations LL103A
thru LL103C.
• For general purpose applications
• Lead (Pb)-free component
• Component in accordance with RoHS2002/95/EC
and WEEE 2002/96/EC
Applications
• HF-Detector
• Protection circuit
• Small battery charger
• AC-DC/DC-DC converters
