Where can I salvage some power MOSFETs?

[Atheus]

I need some big power MOSFETs for a project. I already cleaned out my local electronics shop of these components, and proceeded to fry the lot of them.

I smashed up an old Antec power supply with a hammer, but found that all the big 3-pin semiconductor thingies were 'schottky rectifiers' and not MOSFETS. I was sureit would have some, but apparently not... or maybe they are in a smaller package and I didn't notice them?...

Anyway - does anyone know where there are definately going to be some MOSFETS for me? Monitors perhaps? Aps and radios?

Can't you just buy them?

those are Schottky diodes. So, no luck. Unfortunately, I don't have any good source for FETs. Do you have a part number? There's a junk bin down in our physics building and they may have something. If I can find some when I'm down there monday, I'd be happy to mail them to ya.

You can try something like Digikey or mouser?

Just got a bunch of fets from digikey.
Great price and fast shipping.

I could buy them online and wait a couple days, or just wait for tomorrow and find another electronics shop which I haven't already cleaned out, but I figured if I might have them right here in my piles of electronic crap - why not have a look?

Thanks man, but I assume you're in the USA? Most people here are... but I'm in London. Anyone know a good electronics store in London? Yes I know there are heaps of them, but a 'good' one, like not a Maplins.

Nice idea on the university though. I could try my old compsci department, or the EE labs... but I'm no longer a student. I doubt they will let me rummage through their kit.

Ah. Yeah, I'm in the USA. Unfortunately, I don't know what IC shops are decent in the UK. GL though, you may get an easygoing lab tech at the EE dept who'll have a couple of FETs for ya.

There's a few linked here http://www.cpemma.co.uk/links.html

Crazy to be asking in The States for a London Town source

http://www.bgmicro.com/ has a FET rated at 10A for $0.49.

Pretty much anything switching will have mosfets.. that includes power supplies, audio amplifiers, motor controllers.
