APPLICATIONS
DESCRIPTION
The LH1510 is an SPST normally open switch (1 form A) that
can replace electromechanical relays in many applications.
The relay is constructed using a GaAlAs 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 circuity, and MOSFET switches. In addition,
the relay employs current-limiting circuity enabling it to pass
lightning surge testing as per ANSI/TIA-968-B and other
regulatory voltage surge requirements when overvoltage
protection is provided. The LH1510 is the only relay in the
family that provides current limiting for unidirectional DC
applications.
• General telecom switching
• Instrumentation
• Industrial controls

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.
