Oh no, not an EV argument again, pleaaaaase... I still have not healed from the last one, it's too soon.
Bottom line is : does not matter if one likes them or not, because this week I heard that European parliament or whatever it's called, has voted their law for good now, it's set in stone. By 2035 car manufacturers (motorbikes too ?? Didn't say...), will be allowed to sell only EV, and not even hybrids no, 100% electric.
Let's do something more useful than fighting over something we have no control over, and that's sadly inevitable, by law (an driven by insane petrol prices as well). Well for European citizens at least...
Instead, let's do something nice, helpful, right here right now.... let's help Vince identify this diode.
I have like 3 dozens of them, brand new, that I got in this lot of random junk I got for 10 Euros earlier this year, remember, in the lot was that chinese Vref box.
Zero markings on them, just a clear glass body with two black bands on one side. Yes the cathode is there, but could it be that these two bands are some kind of ancient code that could identify the diode part number, somehow ? Not holding my breath, they will probably all end up in the trash then... but thought hey it's free to ask.
Voltage drop varies quite a bit.. lower than a silicon diode, but a bit high for Germanium. It's like 300 to 450mV, varies quite a bit from one to the next. Schottky ?!
