I want to use a tvs diode for protecting my bench (table that I have on it a set of electronic devices and my pc) from small surges as there is a lot of inductors from where I get my electricity.

A lot of contactors, pumps and motors switching on and off so frequently.

So I connected 2 tvs 350v bidirectional diodes. If my pc is sleeping it will suddenly turn on. That happened also after turning on or off myfan. This happened always with the fan or any AC inductor big enough. I guessed these are surges?

But after using the tvs diodes in parallel near my devices, these disturbance happens less often but didn't fully stop.

I know that I am maybe over reacting so tell me about this. I am just being extra cautious about my expensive devices.

So here is the problem. One of the diodes for 3 consecutive times in a week burned and made a short circuit. By the way I always put a fuse to protect against this scenario and there is a 25A circuit breaker.

What is noticeable is that the usual 3cm(1.2inch) glass 3.75A fuse exploded each time. The 3rd one was the same type but 10A and in a plastic socket I solderd for easy changing. This problem happened in a storm that had a lot of lightning.

And to be honest I am not sure if the first one became faulty during the storm. I just founded my fuse broken into pieces and my tvs diode conducting.

And for more details I always had 1 out of 2 tvs diodes conducting and a broken fuse. The 3rd 10A fuse didn't break into pieces.

I want to put 8 400v tvs diodes in parallel instead of 2. Will this make a change where 8 conduct on high voltage instead of 2?

And I have a theory. Is it possible that when a diode happens to conduct before the 2nd, that it prevents the 2nd one from feeling the high voltage as the 1st one is conducting make the voltage across them 0?
