Dual 1 Form A Solid-State Relay
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.

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)
Breakdown occurs between the output pins external to the package.
(2)
Refer to current limit performance application note for a discussion on relay operation during transient currents.
(3)
Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through
hole devices (DIP).
Note
Minimum and maximum values are testing requirements. Typical values are characteristics of the device and are the result of engineering
evaluations. Typical values are for information only and are not part of the testing requirements.
