Important: using three pin or four pin TO247 packages:

TO247-4L packages can be used without any modification of the PCB. The Kelvin source pin is already connected to the gate-driver ground.

TO247-3L packages however require a minor modification to join the gate-driver ground to the source pin ground. This can be

done by soldering 0

Ω resistors across R19 and R20 or by making a solder bridge between the source and Kelvin source pads

(recommended for lowest gate inductance).
