IS281D-N-AXW

Component

phototransistor optocoupler3750 Vrms isolationSSOP4Grade D CTR80 V output

IS281D-N-AXW is represented by the IS281D-N Grade D high-isolation phototransistor optocoupler family in an SSOP4 package. It provides 300% to 600% CTR and 3750 Vrms isolation.

Best for

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

Avoid if

  • Applications requiring guaranteed high-speed digital isolation
  • Designs that require a documented lifecycle status
  • Use cases where the AXW suffix cannot be supplier-confirmed

Check before use

  • Required CTR at minimum LED drive current
  • Collector voltage and load-current limits
  • Isolation and safety approval requirements
  • SSOP4 land pattern and package orientation
