SCR Output

optotriaczero-crosstriac-driverDIP-6400 V5 kVrms isolation5 mA trigger

HT-3043 is a 400 V, 5 mA-trigger, zero-cross optotriac driver for isolated on/off AC switching with an external power triac.

Best for

  • Isolated AC on/off control
  • Solid-state relay input stages
  • Solenoid and valve control
  • Temperature-control switching

Avoid if

  • Phase-angle dimming
  • Precise AC phase control
  • Applications requiring a power triac integrated in the optocoupler

Check before use

  • External triac voltage and current ratings
  • AC-line surge and dV/dt conditions
  • Gate-drive resistor and snubber design
  • Isolation and creepage requirements
