Triacs are found in nearly every home due to their ability to control AC (Alternating Current) such as the power you'll get from a wall outlet. Unlike a regular transistor that can only transfer electricity in one direction, a triac can handle both positive and negative voltages across its terminals. Likewise, it can be controlled by a gate voltage on the center pin that is either positive or negative. Some of the most popular uses for a Triac include bi-directional DC motor control, AC lamp dimmers & Electric Fan Speed Controllers.
