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  
operatingsystems 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.
