DESCRIPTION
The LH1546 is robust, ideal for telecom and ground fault
applications. It is a SPST normally open switch (1 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 V_RMS
• Typical R_ON 28 
• 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
• Equivalent to CP Clare LCA110
• 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)
