I need advise on best value components for this Reverse Polarity protection schematic (pictured).
source.
The original author just used what he had laying around,
>2N2907A
>IRL2203N
as i will be buying everything new, that gives me a lot of options.
Requirements:
so i dont want to waste money over engineering it.
Cheapest reliable parts will be fine.
im new to electronics & totally confused on how to select the right transistors?
Also do i need to be worried about the volt drop over the mosfet?
