Hello Steve,

Yes, I am using thousands of ST Snubberless Triacs in Traffic control systems, they drive 230/10 volt transformers for halogen lamps up to 5 amps, they are running 24 hours, continuous switching for about 5 years till now, the maintenance records don't show more than 5 Triacs faults in more than 150 traffic controller each has (30-60) Triac.
