LED Indication - Discrete

optocouplerphototransistor outputDIP-45,000 Vrms isolationCTR rank A

HT-817-A-F is a normal DIP-4 phototransistor optocoupler with A-rank CTR of 80% to 160% and 5,000 Vrms isolation.

Best for

  • Isolated logic interfaces
  • Programmable controllers
  • Switching power supply feedback or control interfaces

Avoid if

  • A guaranteed CTR outside the A-rank 80% to 160% range is required
  • A surface-mount package is required

Check before use

  • Confirm CTR over the actual LED drive current and temperature range
  • Confirm output transistor voltage, current, and switching-speed margins
  • Confirm DIP-4 through-hole mechanical fit
