| Mar 3, 2023 at 20:10 | comment | added | Matthew | What do you consider "normal operating power"? TVSs are widely suggested (including by manufacturers) to deal with EMR coil surge; are you disagreeing with that recommendation? | |
| Jan 19, 2023 at 22:53 | comment | added | TonyM | You must see the contradiction, though. | |
| Jan 19, 2023 at 22:02 | comment | added | Tim Williams | I... you're telling my points are wrong. So, finding a contradiction should be a good thing, right??! You aren't giving up anything, are you. | |
| Jan 19, 2023 at 19:07 | comment | added | TonyM | That then contradicts your earlier point. | |
| Jan 19, 2023 at 16:36 | comment | added | Tim Williams | Right, a negative question ("why not..") begets a negative answer ("don't because..."). So you're saying it's in general (the "12 V DC applications" part), not in reply (at all?) to the "such as..." part? | |

| Jan 19, 2023 at 8:26 | comment | added | TonyM | Re-read the question, which asks "Is there a down side..." and "to using bidirectional TVS diodes in 12 V DC applications". That's asking for reasons 'why not' and the answer starts "Usually the reason why not is...". That should clear your confusion. ("it might not be just me" Question's been viewed 110 times so far, I think it's hardly anybody.) | |
| Jan 18, 2023 at 23:19 | comment | added | Tim Williams | Negative, as in, "don't do that"; a generally negative or cautionary sentiment or tone; more cautionary against, than encouraging for, the action asked. I'm not sure that anyone else has [mis]read it in this way, but someone appears to have just upvoted these comments so it might not be just me? | |
| Jan 18, 2023 at 22:41 | comment | added | Tim Williams | As to my reading, this answer seems to give a generally negative response: "usually the reason why not"; "It's not designed for dissipation of normal operating power in a circuit" <-- you don't mention if this case applies to the OP, but mentioning it seems to imply so; "So using a TVS outside of..." <-- similar implication; "So, with a TVS as an operating current clamp..." <-- (read: "to clamp [excess] current" e.g. inductive flyback) saying OP's suggested application is ill suited; have I grossly misread these, and if so, in what way? | |
| Jan 18, 2023 at 22:39 | comment | added | Tim Williams | Well, it's a standalone question in that it's something I've heard (or at least have interpreted by implication) several times here on EESE, and haven't read anywhere else; this answer is just a particular example. Perhaps I should've asked; I apologize. But there are other instances, which asking just here wouldn't have covered. | |
| Jan 18, 2023 at 22:29 | comment | added | TonyM | @TimWilliams, I really don't understand your confusion so I have nothing to clarify, I've written it clearly. Nor do I understand in starting a separate question that refers to this answer without (a) notifying the poster (myself in this case) and/or (b) posting comments here which I would have taken to chat so we could have got somewhere productively. | |
| Jan 18, 2023 at 22:18 | comment | added | Tim Williams | Could you clarify (in both places) to clear up any confusion? Since the question here is repetitive peak service (across a coil etc.) it seems like you're saying a TVS would be perfectly suited here, but you then say "there simply are better alternatives". Or am I also misreading "operating current clamp"? (It's a voltage clamping device, I assume this is just a typo, or implying to clamp excess current?) | |
| Jan 18, 2023 at 22:10 | comment | added | TonyM | @TimWilliams, your linked question refers to my answer yet misquotes it and seems to interpret it wrong. It does appear like you've not read what's written here but seen what you want to see. | |
| Jan 18, 2023 at 21:51 | comment | added | Tim Williams | It's not clear to me that TVS have any reliability problems as long as power or temperature ratings are respected. Further reading: electronics.stackexchange.com/questions/647527/… | |
