Abstract
A triac driving circuit according to an embodiment of the present disclosure includes a phototriac coupler, a first resistive element, and a second resistive element, which are connected in series to a gate terminal of a triac. A minimum resistance of the first resistive element including tolerance is higher than a maximum resistance of the second resistive element including tolerance.
