Michael: I worked at General Semiconductor for about 25 years. I do not know of any specific component safety standard for TVS diode components. The one that we, when at General Semiconductor, had to meet was the UL 497B for telecommunications. Generally, there is no safety standard for individual components. It depends on how they are connected in the circuit and their location, that is for creepage and clearance distances. These components are used on AC power, DC power and data lines. Their selection depends upon specific applications and the peak pulse current and waveform. These two conditions are the only threat conditions that are important. But it is location of the device in the circuit or system that might cause of concern for safety. Dave

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.
