Simple Motor Controller 18v7 Schematic?

I seem to have blown my 18v7 controller, I guess I either overloaded or overheated it (or both). There’re a bunch of little what look like transistors that say 34NA3 on them, and it looks like 2 of them blew. I was kind of wondering what they were so I could replace them.


I’m sorry to hear your controller was damaged. We do not make the schematic for that controller available. At the point where there are multiple components that are visibly damaged, it is likely that there is damage to other components on the board as well, so it is probably not practical to repair. If you contact us via email at, I might be able to get you a small discount toward a replacement.
