High-temperature 8A sensitive Triacs

Specifically designed to operate at 150 °C, the new 8 A T810H TRIACs provide an enhanced performance in terms of power loss and thermal dissipation. This allows the optimization of the heatsink size, leading to space and cost effectiveness when compared to electromechanical solutions.

Based on ST logic level technology, they offer an IGT lower than 10 mA and specified minimal commutation and high noise immunity levels valid up to the Tj max.

Key Features

  • Medium current TRIAC
  • 150 °C max. Tj turn-off commutation
  • Logic level sensitive TRIAC
  • RoHS (2002/95/EC) compliant packages
  • Clip bounding
