  • Available in through-hole package, the T1235T-8T Triac can be used for the on/off or phase angle control function in general purpose AC switching where high commutation capability is required.

    This device can be used without a snubber circuit when the limits defined in this datasheet are respected.

    Key Features

    • Medium current Triac
    • High static and dynamic commutation
    • Three quadrants
    • ECOPACK2 compliant
