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.

Modern CMOS gate oxide layers are ~1nm thick. One electron per microsecond is 150fA, or 0.15pA. Oxide breakdown occurs 1st with a soft nature, then hard breakdown occurs. Soft is when a localized gate oxide conductive path is formed (soft failure device degradation), hard is when this becomes permanent (hard failure device destruction). The effective current levels for these effects are very small!!

Anyway, we should start another topic on this and not disrupt this thread about the new SPD4000X.

Thank you for sharing; I should receive the info from the newsletter but it's nice to have a very timing information from you!
Indeed it is dated 14th of October on Siglent EU website

I think this is good; it make more clear the switch from CV to CC ... if I got it correcltly.

Not sure I like this ... currently I can power on a channel and in a second moment power on all the remaining 3.

I think it sounds safer that way. Less likely to damage stuff.
