Transistor

phototransistor optocoupler5,000 Vrms isolation80 V outputCTR rank ASMD DIP-4RoHS

HT-817S1-ATP1-F is a rank-A SMD phototransistor optocoupler for isolated low-speed control and feedback circuits requiring up to 5,000 Vrms isolation and 80 V output blocking capability.

Best for

  • Isolated PLC and controller inputs
  • Switch-mode power-supply feedback
  • Appliance and meter control isolation

Avoid if

  • High-speed digital isolation beyond the specified optocoupler response range
  • Designs requiring tightly controlled CTR without additional margin

Check before use

  • Minimum CTR at application conditions
  • Output collector current and voltage
  • PCB creepage, clearance, and S1 footprint
  • Current lifecycle and supply status
