photoMOS relayoptocouplerSOP-43750 Vrms isolation200 V AC peak0.18 A

AT175-CuH-S is a SOP-4 optically isolated MOSFET relay for switching loads up to 200 V peak AC and 0.18 A continuous current.

Best for

  • Low-current isolated AC load switching
  • Industrial control interfaces
  • Appliance and security control circuits

Avoid if

  • Loads exceeding 0.18 A continuous current
  • Applications requiring confirmed lifecycle or long-term supply status

Check before use

  • 200 V peak AC load-voltage limit
  • 0.18 A continuous load-current limit
  • 5 Ω maximum on-resistance at the stated test condition
  • Required LED drive current
