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.
