I'm working on an electronics project and decided I need (among other things) an ESD diode to protect my inputs. I selected a diode which should do the trick: https://www.digikey.ca/product-detail/en/vishay-semiconductor-diodes-division/GSOT05C-E3-08/GSOT05C-E3-08CT-ND/1680616
I was going to use this for everything: signal input, Vcc, etc. Looking farther down the Digi-Key page, though, it says: Power Line Protection: No.
The data sheet says the diode can protect "two signal or data lines," and does not claim it will not work on a supply. I see no reason why I can't use the same diode on a 5V Vcc net if I'd use it on a 5V logic net, so what's up with this bizarre "power line protection" stuff? I searched high and low for app notes, etc., but didn't come up with anything.
Any insight into this will be appreciated. If there isn't a satisfactory answer, I'll go ahead and use this "signal/data" diode on my power nets!
