DESCRIPTION
The LH1532 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
LH1532 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.

Notes
• Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. Functional operation 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 the time can adversely affect reliability.
(1)
Refer to current limit performance application note for a discussion on relay operation during transient currents.
