  • Available in SMD, the T1635T-8G Triac can be used for the on/off or phase angle control function in general purpose AC switching where high commutation capability is required. The T1635T-8G can be used without a snubber RC circuit when the limits defined are respected.

    D2PAK package is UL-94,V0 flammability resin compliance.
    Package environmentally friendly Ecopack®2 graded (RoHS and Halogen Free compliance).
    Snubberless™ is a trademark of STMicroelectronics.

    Key Features

    • High static dV/dt
    • High dynamic turn-off commutation (dl/dt)c
    • 150 °C maximum junction temperature
    • Three quadrants
    • Surge capability VDSM, VRSM = 900 V
    • Benefits:
      • High immunity to false turn-on thanks to high static dV/dt
      • Improved turn-off in high temperature environments thanks higher (dI/dt)c
      • Increase of thermal margin due to extended working Tj up to 150 °C
      • Good thermal resistance due to non-insulated tab.
