Does any one remember? It wasn't more than a few months ago. I think that someone was wanting to make a big motor driver and this part was suggested. It was a big, cheap transistor that would handle 40 amps+.
I mentioned in the comments that I was surprised at how few (if any) external parts were needed.
(we might have discussed electric bikes, I dunno)
Telefox was it you?
It wasn’t this post was it?
It wasn’t this post was it? The IRFZ44N MOSFET in that circuit can push up to 50A @ up to 60V =D
Found it! --and it WAS you, Mr. Fox…

It was about electric bikes after all! Man, I gotta get better at bookmarking/collecting stuff.
Yes. Collect. I thelps
Yes. Collect. I thelps others as well

Oops, must’ve gone straight past that one when I was looking for the thread yesterday. Obviously your search-fu is stronger than mine CtC =)
World’s Largest Transistor
Was it that?
