The rated current shall be at least double the expected application. The maximum current is typically defined by the thermal limit of how much heat the part can handle due to IR losses. Note that especially for high current FETs, the max current is given for specific conditions, often at a case (surface) temperature (Tc) of 25C. In reality, it is not realistic to keep the surface of the part at 25C under full load, as this would require sub ambient cooling. Thus, appropriate component derating must be performed.

Grid
All schematics shall be drawn exclusively on a 100 mil grid for neatness. I will be sad if you use a 50 mil grid.
