The BTA12, BTB12 and T12 triac series is suitable for general purpose AC switching. They can be used as an ON/OFF function in applica- tions such as static relays, heating regulation, in- duction motor starting circuits. or for phase control operation in light dimmers, motor speed controllers,. The snubberless versions (BTA/BTB.W and T12 series) are specially recommended for use on inductive loads, thanks to their high commutation performances. Logic level versions are designed to interface directly with low power drivers such as microcontrollers. By using an internal ceramic pad, the BTA series provides voltage insulated tab (rated at 2500VRMS) complying with UL standards (File ref.: E81734).
The BTA12, BTB12 and T12 series are 12 A triacs offered in through‑hole and surface‑mount packages for general‑purpose AC switching, such as static relays, heating regulation, motor starting, light dimming and speed control. The series includes snubberless, logic‑level and standard versions, with voltage ratings of 600 V or 800 V and various gate sensitivities.
The manual lists absolute maximum ratings, electrical and static characteristics, thermal resistance data, mechanical dimensions for D2PAK, TO‑220AB and I2PAK packages, and detailed ordering information including part numbers, packaging types and weight. Revision history and legal disclaimer are also provided.
