Triacs are a very compact solution for switching loads on AC power lines.
Not limited by electromechanical ageing contingencies, triacs have a much longer lifespan compared to relays with circuits respecting specification boundaries.
With a voltage range from 600 to 800 V and up to 1200 V for certain industrial devices, ST's portfolio covers medium-power AC loads with 1 to 50 A triacs.
With a range of driveable AC loads from 120 to 240 V, the list of circuits benefiting from ST triacs includes dimmers, all types of AC mains on-off switches, home or office copy/printer appliances, as well as industrial motor starters or SSRs, gardening tools, automated irrigation systems and a wide variety of automation controllers for factories, buildings and homes.
