Isolators - Gate Drivers

optotriac drivernon-zero-cross600 V15 mA IFTDIP6-S1TRIAC gate drive

HT-3051-S1TA1 is a 600 V non-zero-cross optotriac driver in an S1 surface-mount DIP-6 package. It requires up to 15 mA LED trigger current and is designed to trigger an external power TRIAC.

Best for

  • Phase-angle AC control
  • External TRIAC gate drive
  • Solenoid and valve control
  • AC motor and temperature-control circuits

Avoid if

  • A zero-cross switching function is required
  • The optocoupler must switch the load current directly
  • Available LED drive current is below the required trigger margin

Check before use

  • 15 mA maximum IFT grade at 3 V main-terminal voltage
  • 600 V VDRM suitability for the mains and surge environment
  • External TRIAC gate resistor and snubber network
  • S1 package land pattern and isolation clearance
