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 cir-

cuitry, and MOSFET switches. In addition, the LH1522

SSRs employ current-limiting circuitry, enabling them to

pass FCC 68.302 and other regulatory surge require-

ments when overvoltage protection is provided.

Recommended Operating Conditions

Absolute Maximum Ratings, T =25°C

Stresses in excess of the absolute Maximum Ratings can cause permanent

damage to the device. These are absolute stress ratings only. Functional oper-

ation 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.
