HT-817S1-BTP1-F

Photovoltaic Output

phototransistor optocoupler4-pin SMDCTR rank B5,000 Vrms isolation80 V output

HT-817S1-BTP1-F is a 4-pin SMD phototransistor optocoupler with rank-B CTR and 5,000 Vrms isolation for isolated low-speed control and power-interface signals.

Best for

  • Isolated logic or control interfaces
  • Switching power supply feedback and control circuits
  • Programmable controllers and appliance control boards

Avoid if

  • High-speed isolation beyond the specified optocoupler response capability
  • Applications requiring a tightly controlled CTR without circuit margin
  • Output circuits exceeding 80 V collector-emitter rating

Check before use

  • Design for the minimum 130% CTR rank-B limit
  • Confirm PCB footprint for S1 gull-wing leads
  • Confirm creepage and clearance for the end-system isolation requirement
