EL354A

Photovoltaic Output

phototransistor optocouplerSOP43750 Vrms isolationCTR class A

EL354A is a 4-pin SOP4 phototransistor optocoupler with 3750 Vrms isolation and CTR class A rated from 50% to 150%.

Best for

  • Low-speed galvanic signal isolation
  • Industrial and power control interfaces
  • Phototransistor-based digital input isolation

Avoid if

  • High-speed or precisely timed signal transmission is required
  • The design requires guaranteed lifecycle or supply information not provided in the datasheet

Check before use

  • CTR at the actual LED current and temperature
  • SOP4 pin orientation and PCB footprint
  • Isolation spacing and system insulation requirements
