How To Use BTA12

The BTA12 is a medium power TRIAC with a low holding current, making it suitable for applications like motor controllers and LED dimmers. The BTA12 also has a high surge energy capability, meaning it can handle inductive loads without a snubber. This is possible because of the thermal mass of the die, which absorbs the energy from short pulses before there is a temperature increase. This is shown in the graph of thermal impedance versus pulse duration.
