Application Scenarios & Design Considerations

A.C. INPUT PHOTOTRANSISTOR OPTICALLY COUPLED ISOLATORS

Alternative Part Number

  • TLP521-1 --: Industry-standard single-channel phototransistor optocoupler with similar CTR and isolation ratings, widely available and pin-compatible in most circuits.
  • PC817 --: Very common single-channel optocoupler with comparable current transfer ratio and 5 kV isolation, a direct functional substitute for the IS733H.
  • 4N35 --: General-purpose phototransistor optocoupler with 6-pin DIP package and similar isolation voltage, suitable when a slightly different pinout can be accommodated.
