  • Available in through-hole full pack package, the T635T-8FP 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.

    Provides UL certified insulation rated at 2 kV.

    Key Features

    • Medium current Triac
    • High static and dynamic commutation
    • Three quadrants
    • ECOPACK®2 compliant component
    • Complies with UL standards (File ref: E81734)
