Photovoltaic Output

phototransistor optocouplerSOP43750 Vrms isolationCTR bin B

EL354B is a four-pin AOTE SOP4 phototransistor optocoupler for galvanic signal isolation, specified for 3750 Vrms isolation and 80 V collector-emitter breakdown voltage.

Best for

  • Low-speed digital signal isolation
  • Industrial control interfaces
  • Power-system feedback or status isolation

Avoid if

  • The design requires a guaranteed high-speed logic isolator
  • CTR variation cannot be accommodated

Check before use

  • CTR classification and operating-point margin
  • Pin assignment and LED drive polarity
  • Creepage, clearance, and isolation voltage requirements
