  • The BTA20 Triacs use high performance glass passivated chip technology. The Snubberless concept offers suppression of the RC network and is suitable for applications such as phase control and static switching on inductive or resistive load.

    Thanks to their clip assembly technique, the BTA20 Triacs provide a superior performance in surge current handling capabilities.
    By using an internal ceramic pad, the BTA series provides voltage insulated tab (rated at 2500 V rms) complying with UL standards (File ref.: E81734).

    Key Features

    • IT(RMS)= 20 A
    • VDRM, VRRM= 600 and 700 V
    • IGT (Q1)(max) = 35 and 50 mA
