LAA125PL

Active

Relay, LAA125PL, LITTELFUSE A dual normally open solid state relay that has two independently controlled, optically coupled MOSFET switches with an additional current limiting circuit. The optically coupled combination of MOSFET switches and photovoltaic die provide 3750 Vrms of input/output isolation. The optically coupled outputs, which use the patented OptoMOS architecture, are controlled by a highly efficient infrared LED. This dual switch OptoMOS relay provides a more compact design solution than discrete single-pole relays in a variety of applications, and saves board space by incorporating both switches in a single 8-pin package. Features Low drive power requirements Higher reliability than electromechanical relays Current limiting No EMI/RFI generation Small 8-pin package Flammability rating UL 94 V-0 Applications Telecommunications Instrumentation Multiplexers Data acquisition Electronic switching I/O subsystems Meters Medical equipment Security Industrial controls
