phototransistor optocouplerSSOP-480 V3750 VRMS isolation130% to 260% CTR

VOS618A-8T is a 4-pin Vishay phototransistor optocoupler with a selected 130% to 260% CTR range at 1 mA, 80 V output rating, and 3750 VRMS isolation test rating.

Best for

  • Low-current isolated signal transmission
  • Industrial control interfaces
  • Telecom and programmable-controller circuits

Avoid if

  • A guaranteed high-speed digital isolator is required
  • The design cannot accommodate CTR variation over temperature and operating current

Check before use

  • Confirm required collector current using the minimum 130% CTR bin
  • Check switching times against the output load resistance
  • Observe output voltage, current, power-dissipation, and insulation safety ratings
