The relay is constructed using a GaAlAs LED for actuation control and an integrated monolithic die for the switch output. The die, fabricated in a highvoltage dielectrically isolated technology, is comprised of a photodiode array, switch control circuity, and MOSFET switches. In addition, the relay employs current-limiting circuity enabling it to pass FCC 8.3 and other regulatory voltage surge requirements when overvoltage protection is provided. The LH151 is the only relay in the family that provides current limiting for unidirectional dc applications.

Ozone Depleting Substances Policy Statement LH151AAB/ AABTR/ AT It is the policy of Vishay Semiconductor GmbH to 1. Meet all present and future national and international statutory requirements.. 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 (199) 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. Class I and II ozone depleting substances in the Clean Air Act Amendments of 199 by the Environmental Protection Agency (EPA) in the USA 3. Council Decision 88/5/EEC and 91/9/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 products for any unintended or unauthorized application, the buyer shall indemnify 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.
