Isolators - Solid State Relays

photorelaysolid-state relaySOP-43750 Vrms isolation600 V peak AC40 mA

AT176-CuH-S is a SOP-4 MOSFET-output photorelay for isolated low-current switching up to 600 V peak AC and 40 mA continuous load current.

Best for

  • Isolated low-current AC or DC switching
  • Industrial control interfaces
  • Appliance and security control circuits

Avoid if

  • Loads requiring more than 40 mA continuous current
  • Applications needing low milliohm-level switch resistance
  • Designs requiring documented lifecycle information

Check before use

  • Verify worst-case on-resistance at operating temperature
  • Check peak and continuous load current
  • Confirm creepage and isolation requirements for the end equipment
