I want to do a fet upgrade, but I really don't like ordering online
I went to the RS website, and it seems all they have are IRF510's and are only N-channel (I think). I went to the xmods science, and I read that the FETs used could handle like hundreds of amps, and I am wondering if you really need all that for an xmod (a plasma dash, found elsewhere, draws up to 1.8 amps w/o load.) At digikey the chart said the IRF510's can handle up to 5.6 amps, and that seemed reasonable to me. Here's the question: can I use the IRF510's without any disadvantage other than on-resistance (I'm hoping it's low) on my xmod? I might be using a plasma dash, or maybe even an Auldey panther (faster, I think). And can I get P-channel fets from RS? Why do I need both N and P? Forward and reverse?
