[QUOTE="Vipersan, post: 914278, member: 325666"] Still in persuit of a solution .. Varistors seem a good idea ..but then do degrade over time as the (oxide grains) are exposed to transients.. apparently ...and I do find great difficulty in understanding the various ratings/attributes. They do however perform like a non polarised zener diode in many respects..but apparently there are TVS diodes which may also do the job.. These being back to back zeners in one package ...thus not polarised ..?? Never used such a thing ..ever .. Has anyone reading this ...? I wonder if I can then use 2 of these thusly ... From what I can gather reading about them ... They do still have a bias Protecting against a larger +ve going transient in one direction ...and a lesser -ve transient in the other .. A photo of such a diode still shows a stripe at one end as if to indicate the diode has a direction ?? So 2 in parallel one of them up ended ?? Will this work ?
