Execess of current due to the overvolatge can and will damage/destory certain components ...

Actually the overvoltage can without much current at all. CMOS Gate Oxides fail due to voltage, they are so thin today, a few atoms thick, that it doesn't take much voltage (or current) to puncture the oxide and cause a failure, and in it takes very very little current for this puncture to happen :P

BTW BJTs are also susceptible, altho they tend to take more current as the usual failure mode is localized heating. A couple decades ago we were dealing with 400~500GHz SiGe BJTs in a BiCMOS process that had junction breakdowns below 2V, you could fry these by just looking at them it seemed....exteremely sensitive to any over voltage.

Of course as always YMMV!!

Let me insist :)
Voltage does not flow, Voltage is potential difference or as Fluke states "Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop" https://www.fluke.com/en/learn/blog/electrical/what-is-voltage
Wikipedia "Voltage, also known as (electrical) potential difference, electric pressure, or electric tension is the difference in electric potential between two points." https://www.google.com/url?sa=t&source=web&rct=j&opi=89978449&url=https://en.wikipedia.org/wiki/Voltage&ved=2ahUKEwiNiNjl5_yIAxW9cfEDHUD3Id4QFnoECDwQAQ&usg=AOvVaw313bQM2LG1bdUNXXllrJqE
Even a smal potential difference might make an electron moves.
Electrons move and can damage things

Yes electrons move and can damage things, and how much current is a few electrons moving thru a thin oxide  ;)

My SPD4323X has arrived. From playing with it for a few moments it seems to be a good product overall. The buttons and encoder don’t feel as high quality as my SDS800X-series scope, but they are definitely useable. I am keen to start using it!

Enjoy it but move it on the bench; can't see it on the floor!  8)
Indeed I like the "clicky" encoder.
Share your opinion soon.

1eV=1.602*10^-19 J
1[C]=6.25*10^18 electrons
Q= algebric sum of electrical charges

8) ... anyway I have to admit I am not aware of phisical characteristics of oxide.
