This document introduces the main features of the BTA12, BTB12 and T12 series triacs, including application scenarios, package types, pin definitions, and specifications.
The BTA12, BTB12 and T12 series are 12 A triacs offered in both through‑hole and surface‑mount packages for general‑purpose AC switching. They are suitable for applications such as static relays, heating regulation, induction‑motor starters, light dimmers and motor‑speed controllers. Snubberless versions are recommended for inductive loads, while logic‑level versions can be driven directly by low‑power drivers.
The document provides absolute maximum ratings, electrical and thermal characteristics, mechanical dimensions, ordering codes and packaging options. It also includes revision history and legal disclaimer information.
