SGS-THOMSON BTA12/BTB12 BW/CW Snubberless Triac Datasheet
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.
