This document mainly introduces the characteristics of BTA40/41 series products, including main characteristics, package form, order codes, absolute maximum ratings, electrical characteristics, etc.
The BTA40, BTA41 and BTB41 series are 40 A TRIACs offered in high‑power packages for general‑purpose AC switching. They are suitable for applications such as static relays, heating regulation, induction‑motor starting, light dimmers and motor‑speed controllers. The series includes insulated (TOP3) and non‑insulated (RD91) variants with voltage ratings of 600 V and 800 V.
The document lists absolute maximum ratings, electrical and static characteristics, thermal resistance data, and mechanical dimensions for the different package types. Ordering information, part‑number conventions, and packaging options (tube or bulk) are also provided, along with revision history and legal disclaimer.
