Photovoltaic Output

phototransistor optocoupler4-pinCTR rank D5,000 Vrms isolationDIP S1

HT-817S1-DTP1 is a 4-pin phototransistor optocoupler with CTR rank D, 5,000 Vrms isolation, and an 80 V collector-emitter rating.

Best for

  • Galvanic signal isolation
  • Controller and power-supply interfaces
  • Phototransistor switching applications

Avoid if

  • The design requires a specified lifecycle or supply guarantee not provided in the inputs

Check before use

  • CTR margin at the actual LED current and collector voltage
  • Isolation test conditions and PCB creepage requirements
  • Package and assembly compatibility for the S1 variant
