DESCRIPTIONThe 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.
