Description
• Component in accordance to RoHS 2002/95/EC
and WEEE 2002/96/EC
The LH1526 relay is two SPST normally open
switches that can replace electromechanical relays in
many applications. The relays require a minimal
amount of LED drive current to operate, making it
ideal for battery powered and power consumption
sensitive applications. The relay is constructed using
a GaAIAs LED for actuation control and an integrated
monolithic die for the switch output. The die is, fabri-
cated in a high-voltage dielectrically isolated technol-
ogy, comprised of a photodiode array, switch-control
circuitry, and MOSFET switches. In addition, the relay
employs current-limiting circuitry, enabling it to pass
FCC 68.302 and other regulatory surge requirements
when overvoltage protection is provided. The relay
can be configured for ac/dc or dc-only operation.

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.
