DESCRIPTION
The LH1540 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 lightning
surge testing as per ANSI/TIA-968-B 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 350 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)
