DESCRIPTION
The LH1522 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 LH1522
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. These are absolute stress ratings only. 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.
