Hi all, new member here. I stumbled across this forum while doing some research for a project, and I thought maybe one of you could help me out.
I've got a 9V, 3A circuit where I want to use the equivalent of a JFET (or what I understand a JFET does, anyway)--that is, have an electrically-controlled switch that's normally closed and passes current, but becomes open when I apply a control voltage to it.
The problem is that all the JFETs I've found on Mouser, Digikey, and Jameco have a maximum load current measured in mA, and nothing even approaches 3A.
Is there a cheap component that can do what I need, or am I looking at investing in some fairly pricey relays here?
