HT-817-D-F

Transistor

phototransistor optocouplerDIP-45,000 Vrms isolation80 VCTR rank D

HT-817-D-F is a DIP-4 phototransistor optocoupler with rank-D CTR of 300% to 600%, 5,000 Vrms isolation, and an 80 V output rating.

Best for

  • Isolated low-speed control signals
  • Programmable controllers
  • Switching power supply feedback or control circuits

Avoid if

  • Tightly controlled CTR without circuit margin
  • High-speed isolation beyond the specified phototransistor response capability
  • Applications requiring an explicitly confirmed lifecycle status

Check before use

  • CTR rank D: 300% to 600% at IF=5 mA and VCE=5 V
  • 5,000 Vrms isolation test condition and board-level creepage requirements
  • 80 V collector-emitter rating and 50 mA collector-current maximum
