Abstract
A triac (100) utilizes an FET (107) to inhibit firing of a transistor (112) that forms a portion of the SCR of the triac (100). A DMOS transistor (106) is used to supply a substantially constant bias current to the transistor (107) in order to facilitate rapid turn-on of the transistor (107) around the zero-crossing of the voltage applied to the triac (100).
