Hoping someone could give me hand with this concept.
I need to switch AC to a load based upon a small voltage input of variable amplitude.
My idea was to use a FET, with the input at the gate, load(consider it a lightbulb) between 120AC and the drain, and the source straight to ground/ the dead half of a household AC plug.
I'm concerned about transistor selection, and the potential for reverse biasing on the negative swing of the 120AC.
Any input is appreciated.

Thanks!
Wasn't aware of this component. Looks perfect.
