  • Available in through-hole or surface mount packages, these Triac series are suitable for general purpose mains power ac switching.

    These 20 A Triacs provide a very high switching capability up to junction temperatures of 150 °C.
    The heatsink can be reduced, compared to traditional Triacs, according to the high performance at given junction temperatures.
    By using an internal ceramic pad, the TO-220AB insulated version provide voltage insulation (rated at 2500 VRMS).
    The surface mount D²PAK package enables compact SMD based designs for automated manufacturing.

    Key Features

    • Medium current Triac
    • 150 °C max. Tj turn-off commutation
    • Low thermal resistance with clip bonding
    • Very high 3 quadrant commutation capabilities
    • Packages are RoHS (2002/95/EC) compliant
    • UL certified (ref. file E81734)
