All: You are correct, but this is generally due to the cost of the TVS diode and the MOV, not the capability. Dave

I want to thank all those who replied for their responses. We have a lot to think over. To answer questions posed: The concept is to find an alternative to MOVs for surge protection. The attraction to the Transient Voltage Suppressors is their reliability and current clamping characteristics. General Semiconductor (now Vishay) does have a few "mains" rated, UL approved TVSs. They are rated to 120 VAC which doesn't make them useful for European voltages. The engineer I spoke with for Vishay informed me that they are contemplating UL approvals for their 400 and 440 TVSs up to those voltages. Based on the response, TVSs do not appear to be a popular method of transient protection on the power line.

Greetings, Is anyone aware of Transient Voltage Suppressors (General Semiconductor calls them TransZorbs) with any European safety approvals (Semko, Demko, VDE, etc.,)? They would need to be rated for mains voltage.
