Qxx10 Standard/Alternistor 10A Triacs

Littelfuse Qxx10 Standard and Alternistor (High Commutation) 10A Triacs are bi-directional solid-state switches designed for AC switching and phase control applications. The Qxx10 components are UL recognized to UL 1557 as Electrically Isolated Semiconductor Devices. Isolated packages offer an internal construction with the case or mounting tab electrically isolated from the semiconductor chip. The Qxx10 standard type devices normally operate in Quadrants I and III triggered from the AC line. The alternistor versions are also used in applications requiring high commutation performance such as controlling inductive loads.
