Semiconductor diode?

[Mikeyman64]

I need a semiconductor diode, but I don't have time to go to Radio shack any time soon. But I've got 2 busted mobos that I can rip parts from, one's a PSOne mobo and the other is an Atari 2600 mobo. Do you guys know where on those mobos a semiconductor diode might be? I need it to keep 12V DC from touching my 7.2V Infolithium battery just to let you know.

BTW: I'm almost done with my NOACp (temp name)! It runs PERFECTLY, I just have to tweek it up and get any bug that are in there exterminated. Then I'll post it in the News section.

Hate to be a pest, but isn't a diode a semiconductor? Any diode is a semiconductor diode, isn't it? And to keep voltage off your battery, why don't you just wrap your battery in an insulator or something?

What do you mean by "touching"?

Nevermind, I found a pack of 50 a Radio Shack.

nope, a diode itself is not a semiconductor. All diodes are made using semiconductor material though. I havent taken the semiconductor physics course yet, but I do know that silcon is the type of semiconductor that is most widely used. It's called a semiconductor because...well...it only somewhat conducts electricity in its intrinsic state. To make a silicon diode they dope the silicon lattice with electron acceptor atoms or electron donor atoms, creating a P-type or N-type material. When the P and N types are put together, you get the famous P-N junction that makes diodes possible, where things diffuse and drift and a voltage potential is created and all sorts of other junk that i still dont understand fully.

Anyway, thought i'd clear that up

Wow. I just read all that (phrased differently) on wiki. You smart.

[codeman]

haha...well i'm paying a lot of money to try to get smart, so i'm glad it's sort of working

I know I'll be there someday.
