BTA140B series is glass passivated triacs produced by Philips Semiconductors. The package is suitable for surface mounting. The series of thyristors are suitable for applications requiring high bidirectional transient and blocking voltage capability and high thermal cycling performance. Typical applications include motor control, industrial and domestic lighting, heating and static switching.
The Philips BTA140B series triac is a glass‑passivated device in a surface‑mount SOT404 package, intended for motor control, lighting, heating and static switching applications. It offers high off‑state voltage capability (up to 800 V) and robust on‑state current handling (25 A RMS, 190 A non‑repetitive peak).\n\nThe document provides full electrical characteristics, thermal resistance values, static and dynamic performance data, as well as mechanical dimensions, mounting instructions and safety notes. All specifications are given according to IEC 134 absolute maximum rating system.
