DESCRIPTION
APPLICATIONS
The LH1550 is robust, ideal for telecom and ground fault
applications. It is an SPST normally open switch (1 form A)
that replaces electromechanical relays in many applications.
It is similar to the LH1540, but has a characteristically higher
On resistance. It is 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, it employs current-limiting circuitry
which meets lightning surge testing as per ANSI/TIA-968-B
and other regulatory voltage surge requirements when
overvoltage protection is provided.
• 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.
(1) Refer to current limit performance application note 58 for a discussion on relay operation during transient currents.
(2) Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through
