Transistor

photocoupleroptocouplerphototransistorDIP-4CTR rank C5000 Vrms isolation

HT-817-C-F is a normal DIP-4 phototransistor optocoupler with CTR rank C, specified at 200% to 400% under IF=5 mA and VCE=5 V.

Best for

  • Galvanically isolated logic or low-current control signals
  • Programmable controllers
  • Switching power supplies and appliance controls

Avoid if

  • High-speed isolation beyond the specified 80 kHz typical cutoff frequency
  • Applications requiring a guaranteed CTR outside rank C
  • Designs requiring confirmed lifecycle or traceable approval status without further verification

Check before use

  • CTR margin at actual LED current and temperature
  • Output transistor voltage and current dissipation
  • Normal DIP-4 lead geometry and 2.54 mm pitch
  • Exact compliance and safety-approval requirements
