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 lightning
surge testing as per ANSI/TIA-968-B and other regulatory
surge requirements when overvoltage protection is
provided.
