HT-3083

Component

optotriaczero crossing800 V5 kVrms isolationDIP-6AC control

HT-3083 is an 800 V zero-crossing optotriac driver with 5 kVrms isolation and 5 mA maximum trigger current for controlling an external AC power triac.

Best for

  • Isolated on/off control of AC loads through an external power triac
  • Low LED-drive-current logic interfaces
  • Zero-cross solid-state relay and industrial-control designs

Avoid if

  • Direct switching of a load without an external power triac
  • Phase-angle dimming or other non-zero-cross triggering applications
  • Applications requiring an explicitly documented lifecycle status

Check before use

  • Confirm the 5 mA maximum IFT requirement across temperature and production margin
  • Check external triac gate sensitivity and commutating dv/dt behavior
  • Observe the 100 mA RMS output-current limit
  • Keep pin 5 unconnected as indicated by the datasheet
