When unbricking a Galaxy Note 5 by flashing a firmware using Odin, you may need PIT file sometimes when partitions get bad on your device. That usually happens when you flashed a wrong firmware on your device. using a PIT file fixes the partition sector of the device, telling device correct which partition belongs to what with what size.
