IS280A-N-AXW

Component

AC-input optocouplerphototransistor output3750 Vrms isolationSSOP480 V

IS280A-N-AXW is an ISOMICRON SSOP4 AC-input phototransistor optocoupler specified for 3750 Vrms isolation and 50% to 150% CTR.

Best for

  • Isolated AC signal sensing
  • Low-speed isolated control interfaces
  • Switch-mode power-supply feedback or control circuits

Avoid if

  • A guaranteed CTR tighter than 50% to 150% is required
  • High-speed isolation is required
  • The undocumented AXW suffix cannot be verified

Check before use

  • CTR at the actual LED current and temperature
  • Output voltage, current, and dissipation margins
  • SSOP4 footprint and pin orientation
  • Purchased-part suffix and reel marking
