IS181A-AXW

Transistor

optocouplerphototransistor outputSOP-43750 Vrms isolation80 VCTR rank A

IS181A-AXW is a 4-pin SOP optocoupler with phototransistor output, 3750 Vrms isolation, and A-rank CTR of 80% to 160% at 5 mA LED current.

Best for

  • Isolated low-speed switching signals
  • Switch-mode power-supply feedback and control
  • Programmable controller interfaces

Avoid if

  • A guaranteed high-speed digital isolator is required
  • The design cannot tolerate CTR variation

Check before use

  • Minimum CTR at actual LED drive current
  • Output load and saturation condition
  • Isolation and PCB creepage requirements
