BTA/BTB12 and T12 series SNUBBERLESS™, LOGIC LEVEL & STANDARD 12A TRIACS are general purpose AC switching devices from STMicroelectronics. They can be used as an ON/OFF function in applications such as static relays, heating regulation, induction motor starting circuits. or for phase control operation in light dimmers, motor speed controllers,.
This document provides a technical overview of the BTA/BTB12 and T12 series TRIACs manufactured by STMicroelectronics. These devices are suitable for general-purpose AC switching applications, including static relays, heating regulation, induction motor starting circuits, light dimmers, and motor speed controllers.
| RMS on-state current (full sine wave) | 12 A |
|---|---|
| Non repetitive surge peak on-state current | 120 A (50 Hz) |
| Peak gate current | 4 A |
| Average gate power dissipation | 1 W |
They can be used as an ON/OFF function in static relays, heating regulation, induction motor starting circuits, or for phase control operation in light dimmers and motor speed controllers.
The snubberless versions (BTA/BTB...W and T12 series) are specially recommended for use on inductive loads due to their high commutation performances.
Logic level versions are designed to interface directly with low power drivers such as microcontrollers.
