Hi all,
im designing a battery shut off switch using mosfets in a pack size of 2.5in width and 5in length i have in mind 4 layer pcb with 2 inner power plane one power plane connected to drain of the mosfet and the second power plain connected to source of the mosfet each power plane is 15 oz of copper and the external layer (Top.Bottom) 4 oz copper. is this sufficient for 300amp continuous with these copper sizes
