PAA191 - Normally Open OptoMOS Relays

General Description

PAA191 is a dual 400V, 250mA, 8 normally open (1-Form-A) solid state relay that uses optically coupled MOSFET technology to provide 5000Vrms of input to output isolation.

Its optically coupled outputs, which use the patented OptoMOS architecture, are controlled by a highly efficient infrared LED.

Key Features

  • 5000Vrms Input/Output Isolation.
  • Low Drive Power Requirements.
  • Greater Reliability than Electromechanical Relays.
  • No EMI/RFI Generation.
  • Small 8-Pin Packages.
  • Flammability Rating UL 94 V-0.
  • Surface Mount Tape & Reel Version Available.
