IS281A-N-AXW

Photovoltaic Output

optocouplerphototransistor outputSSOP43750 Vrms isolation

IS281A-N-AXW is a 3750 Vrms isolated transistor-output optocoupler in a 4-pin SSOP package, with an 80–160% CTR grade under the specified test conditions.

Best for

  • Galvanically isolated digital or low-speed control signals
  • Switch-mode power supplies and industrial control equipment

Avoid if

  • The design requires a logic-gate output or tightly controlled CTR without margin
  • The application exceeds the stated isolation, voltage, current, or temperature ratings

Check before use

  • CTR over the full LED-current and temperature range
  • PCB creepage, clearance, and SSOP4 footprint
  • Collector load and switching-speed requirements
