ST's triacs designs and manufacturing technology set the industry standards for a wide range of medium-power TRIACs. Standard and Snubberless triacs belong to our STPOWER family.
Our 3-quadrant 1200 V triacs target industrial 3-phase equipment with secured transient immunity.
ST's 600-800 V 3Q and 4Q triacs have 5 to 50 mA gate options on a 0.8 to 40 A span of current ratings. The package range covers surface-mount SMB flat to ceramic-insulated heavy-duty TOP-3 packages (T2650-6PF, T4050-6PF).
The diac is both a phase-angle trigger complement for triacs in dimmers and an ignition sequence helper in power supplies of lighting electronics such as compact fluorescent lamps (CFL), tube lamps (TL), and LED lighting solutions.
ST’s 8H Triacs have been designed for Industrial, Building, Residential, Appliances. Based on the new ST’s technology, the 8H Triacs are able to work at 800V & 150°C without compromise. It makes 8H Triacs the right choice to run in very hot confined electronic environment and improve the reliability of your system. Thanks to 8H Triacs robust dynamic turn-off commutation and high noise immunity at high temperature you can reduce your system size while increasing functional safety.
