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)-V to
SD103CW(S)-V, and in the
MiniMELF case with type
designations LL103A thru LL103C
For general purpose applications
AEC-Q101 qualified
Material categorization: For definitions of compliance
