Triacs designed for applications including AC mains and appliances

Available now from Digi-Key, STMicroelectronics' triacs are used to control AC mains applications. They can be used as simple on/off switches, to replace electromechanical relays while providing a higher degree of flexibility (through electronic control) and superior reliability. Using a simple phase-control circuit, they can also be used to control the power level through AC loads. The company’s portfolio includes devices with voltage ratings up to 800V and RMS on-currents up to 40A in general-purpose standard configurations, a high-commutation T series in Snubberless technology, and high-temperature triacs for use in harsh environments. They are the reference for universal motor drivers in appliance applications due to their ability to manage the inrush conditions when driving inductive loads. The devices are available in plastic moulded or ceramic isolated and non-isolated, through-hole power packages as well as surface-mount packages.
