So here's my situation: I'm a mechanical engineering student working on a product innovation for one of my courses. The product itself is fairly heavy into embedded programming, which I'm comfortable with. What I'm less comfortable with is the small electrical engineering bit I need to do.
Essentially, I need to be able to control (turn on or off) a high-speed (USB) data line via transistor (or SSR, if you want to be pedantic). When a high signal is sent to the (base or gate), the line is enabled, and data can flow. When there is a low present, the communication is disabled.
Because I'm dealing with very low current flow, my inclination is to use an NPN transistor, mostly because I have a few handy. Is there a better transistor or special rating I should be looking for for this application?
