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