Component

photocouplerphototransistor outputDIP-4 S1CTR rank C5,000 Vrms isolationRoHS

HT-817S1-CTP1 is a DIP-4 S1 phototransistor optocoupler with rank-C CTR of 200% to 400%, 5,000 Vrms isolation, and 80 V collector-emitter capability.

Best for

  • General-purpose isolated digital or low-current control interfaces
  • Programmable controllers and intelligent meters
  • Switching power-supply feedback or control circuits

Avoid if

  • Applications requiring a guaranteed high-speed digital isolator
  • Designs that cannot tolerate phototransistor CTR variation
  • Use above 80 V collector-emitter voltage

Check before use

  • Design to the minimum CTR rank-C value
  • Confirm creepage, clearance, and insulation requirements for the assembled PCB
  • Validate switching timing with the actual collector load resistance
