The BTA/BTB08 and T8 triac series are suitable for general purpose AC switching. They can be used as an ON/OFF function in applications such as static relays, heating regulation, and induction motor starting circuits. The snubberless versions are recommended for use on inductive loads due to their high commutation performances.
The BTA/BTB08 and T8 triac series from STMicroelectronics are general‑purpose AC switching devices. They are used in static relays, heating regulation, induction‑motor starting circuits, light dimmers, and motor speed controllers, with snubberless versions recommended for inductive loads.
The datasheet lists key specifications such as 8 A RMS on‑state current, voltage ratings of 600 V/800 V, various package options (DPAK, IPAK, TO‑220AB), thermal resistances, and detailed ordering codes. Mechanical dimensions and footprint data are also provided for PCB layout.
