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.

Q Series Switching Thyristors

Littelfuse Q Series Switching Thyristors are bidirectional, solid-state protection devices designed to handle loads from 0.8A to 40A_RMS with 10mA, 25mA, and 50mA IGT in operating Quadrants I, II, III, and IV. Littelfuse developed the Q Series Switching Thyristors for a wide range of AC applications to control AC power either through full-cycle switching or phase control of current to the load element. Q Series devices are rated to block voltage in the OFF condition from 200V minimum with selected products capable of 1000V operation. Internally-constructed, isolated packages are available for ease of heat sinking with highest isolation voltage.
