SD103AW-V/103BW-V/103CW-V
Vishay Semiconductors
Small Signal Schottky Diodes
Features
• 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.
• The SD103 series is a metal-on-silicon Schottky
barrier device which is protected by a PN junction
guard ring.
• This diode is also available in the MiniMELF case
with the type designations LL103A to LL103C,
DO35 case with the type designations SD103A to
SD103C and SOD323 case with type designations
SD103AWS-V to SD103CWS-V.
• For general purpose applications.
• Lead (Pb)-free component
• Component in accordance to RoHS 2002/95/EC
and WEEE 2002/96/EC

Ozone Depleting Substances Policy Statement
It is the policy of Vishay Semiconductor GmbH to
1. Meet all present and future national and international statutory requirements.
2. Regularly and continuously improve the performance of our products, processes, distribution and operating
systems with respect to their impact on the health and safety of our employees and the public, as well as
their impact on the environment.
It is particular concern to control or eliminate releases of those substances into the atmosphere which are
known as ozone depleting substances (ODSs).
The Montreal Protocol (1987) and its London Amendments (1990) intend to severely restrict the use of ODSs
and forbid their use within the next ten years. Various national and international initiatives are pressing for an
earlier ban on these substances.
Vishay Semiconductor GmbH has been able to use its policy of continuous improvements to eliminate the use
of ODSs listed in the following documents.
1. Annex A, B and list of transitional substances of the Montreal Protocol and the London Amendments
respectively
2. Class I and II ozone depleting substances in the Clean Air Act Amendments of 1990 by the Environmental
Protection Agency (EPA) in the USA
3. Council Decision 88/540/EEC and 91/690/EEC Annex A, B and C (transitional substances) respectively.
Vishay Semiconductor GmbH can certify that our semiconductors are not manufactured with ozone depleting
substances and do not contain such substances.
We reserve the right to make changes to improve technical design
and may do so without further notice.
Parameters can vary in different applications. All operating parameters must be validated for each
customer application by the customer. Should the buyer use Vishay Semiconductors products for any
unintended or unauthorized application, the buyer shall indemnify Vishay Semiconductors against all
claims, costs, damages, and expenses, arising out of, directly or indirectly, any claim of personal
damage, injury or death associated with such unintended or unauthorized use.
