But the thing is, the arrow couldn't have a particularly powerful EMP anyway, because if it was too bulky, it'd mess up the aerodynamics. I think the the Iron Man suits could possibly act as Faraday cages, absorbing the small amount of energy released by the arrow. Tony Stark is meant to be a genius, I doubt he'd leave his suits susceptible to such an obvious weakness.

That is what I meant. Not strong enough to do a lot of damage. None at all.
