Been a while since I took an EE class so Im not sure if Im thinking correctly here...
Just to give you some background on what Im trying to do first; I am putting power windows in my car and I have a keyless entry system with an extra channel to control something. I want to be able to roll down both windows from my remote using one relay, and one wire to power both windows. I know this could easily be done with 2 relays, but I am trying to keep my already complex wiring system as simple as possible.
So, I can easily get a diode rated for 6amps @200v. Does this translate to a higher amperage rating at a lower voltage? If I work out an inverse proportion, it comes out to a wildly high amp rating (400A) @12v. Math was and still is never my strong suit so feel free to correct me here.
All I need the diodes to do is keep the window wires independent from each other when Im using the switches in the car. So maybe the little 6A diode is enough? I tend to over build my electronics.
