The BTA12 BW/CW and BTB12 BW/CW are snubberless triacs from the SGS‑Thomson family, featuring high commutation speed and high surge current capability without the need for external snubber networks. They are intended for phase‑control and static‑switching applications with resistive, inductive or capacitive loads.
The document provides detailed absolute ratings, thermal resistance data, gate and electrical characteristics, ordering information and mechanical dimensions for the TO220AB plastic package. Key parameters such as on‑state RMS current, peak surge current, off‑state voltage rating and recommended mounting torque are listed for design reference.
