1 Form A Solid State Relay
DESCRIPTION
The LH1535 is robust, ideal for telecom and ground fault
applications. It is an SPST normally open switch (form A)
that replaces electromechanical relays in many applications.
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 FCC 68.302
and other regulatory voltage surge requirements when
overvoltage protection is provided.
FEATURES
• Current limit protection
• Isolation test voltage 5300 VRMS
• Typical RON 20 max. 25
• Load voltage 400 V
• Load current 120 mA
• High surge capability
• Clean bounce free switching
• Low power consumption
• SMD lead available on tape and reel
• Compliant to RoHS Directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
APPLICATIONS
• General telecom switching
• Instrumentation
• Industrial controls
Note
• See "solid state relays" (application note 56)

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.
(2) Refer to reflow profile for soldering conditions for surface mounted devices (SMD). Refer to wave profile for soldering conditions for through hole
devices (DIP).
Notes
• 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.
(1) No DC mode current limit available.
