LH1520AB/ AAC/ AACTR

Vishay Semiconductors

Description

The LH1520 dual 1 Form A relays are SPST normally
open switches that can replace electromechanical
relays in many applications. They are constructed
using a GaAIAs LED for actuation control and an inte­grated monolithic die for the switch output. The die,
fabricated in a high-voltage dielectrically isolated
technology is comprised of a photodiode array, switch
control circuitry, and MOSFET switches. In addition,
the LH1520 SSRs employ current-limiting circuitry,
enabling them to pass FCC 68.302 and other regula­tory surge requirements when overvoltage protection
is provided.

Absolute Maximum Ratings, T

Stresses in excess of the absolute Maximum Ratings can cause permanent damage to the device. Functional operation of the device is
not implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
Maximum Ratings for extended periods of time can adversely affect reliability.

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.
