supposedly IRZL44N, IRF4905 can handle handle 50 AMPS and even more?
using a PCB track width calculator.

a standard pcb has 18μm copper thickness.
3 amps requires 5.288 mm width!
but the mosfets are packaged in TO-220.
I can reach the pins with max 1.905 mm track width and have some space between them.
So i could max do 1.4 amps with 1.905 mm track width
How they do that?
Do they thin metal leads of the TO-220 package (IRZL44N, IRF4905) handle something like 50 amps?
