BTA12 BW/CW BTB12 BW/CW is a high-performance glass passivated chip technology triac family from STMicroelectronics. This triac family has excellent switching performance and is suitable for applications such as phase control and static switching on inductive or resistive loads.
This document provides technical specifications for the BTA12 BW/CW and BTB12 BW/CW snubberless triac family. These high-performance glass passivated chips are designed for phase control and static switching applications on inductive or resistive loads without the need for an RC snubber network. The devices support a surge current of 120A and a repetitive peak off-state voltage up to 800V.
