Small Signal Schottky Diodes
MECHANICAL DATA
Case: DO-35
Weight: approx. 125 mg
Cathode band color: black
Packaging codes/options:
TR/10K per 13" reel (52 mm tape), 50K/box
TAP/10K per ammopack (52 mm tape), 50K/box
FEATURES
• The SD103 series is a metal-on-silicon Schottky
barrier device which is protected by a PN
junction guardring
• 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 SOD-123 and
SOD-323 case with type designations SD103AW(S) to
SD103CW(S), and in the MiniMELF case with type
designations LL103A thru LL103C
• For general purpose applications
• AEC-Q101 qualified
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
• HF-detector
• Protection circuit
• Small battery charger
• AC/DC, DC/DC converters
