Component

optocouplerphototransistor outputDIP S1galvanic isolation

HT-817S1-ATP1 is a 4-pin DIP S1 optocoupler using an LED and phototransistor for galvanic signal isolation.

Best for

  • Galvanically isolated digital signals
  • Programmable controllers
  • Switching power supplies
  • General-purpose appliance control

Avoid if

  • A logic-level optocoupler with tightly specified CTR over temperature is required
  • The application exceeds the stated voltage, current, isolation, or temperature limits

Check before use

  • CTR rank and test conditions
  • LED drive current and phototransistor load
  • PCB dimensions and pin orientation
  • Required safety and isolation certification
