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).
TheMontrealProtocol(1987)anditsLondonAmendments(1990)intendtoseverelyrestricttheuseofODSsand
forbidtheirusewithinthenexttenyears.Variousnationalandinternationalinitiativesarepressingforanearlierban
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. AnnexA,BandlistoftransitionalsubstancesoftheMontrealProtocolandtheLondonAmendmentsrespectively
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-Telefunken products for any unintended or unauthorized
application, the buyer shall indemnify Vishay-Telefunken 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.
