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.

QJxx10 High Temp Alternistor/Standard Triacs

Littelfuse QJxx10 High-Temperature Alternistor/Standard (High Communication) Triacs are offered in TO-220AB, TO-220 isolated, and TO-263 packages with a +150°C maximum junction temperature and 120A ITSM at 60Hz. These devices enable easier thermal management and higher surge handling capability in AC power control applications such as heater control, motor speed control, lighting controls, and static switching relays. The alternistor version TRIACs (no snubber required) operate in quadrant I, II, and III, while offering high performance in applications requiring high commutation capability. The standard type devices normally operate in Quadrants I and III triggered from the AC line.
