Transistor

phototransistor optocouplerSOP-4B CTR rank3,750 Vrms isolation80 V output

HT-357-BTP1 is a SOP-4 phototransistor optocoupler with B-rank CTR of 130% to 260%, 3,750 Vrms isolation, and 80 V output rating.

Best for

  • Isolated digital or low-current control interfaces
  • Programmable controllers
  • Switching power-supply feedback or control circuits
  • Appliance and meter control

Avoid if

  • Applications requiring guaranteed high-speed switching beyond the stated response-time conditions
  • Designs that require a tightly controlled CTR over all operating conditions

Check before use

  • CTR margin at actual IF and temperature
  • Output load line and saturation voltage
  • Isolation and PCB creepage requirements
  • SOP-4 pad layout and assembly profile
