I am doing a sym and footprint for the SISA40DN NFET. This has 5 drain pads, 3 source pads and one gate pad.
Is it OK to just do a symbol with three pins (G,D & S), and then in the pin number field for the drain pin, put “5,6,7,8,9”…to show that the drain pin should connect to pads 5,6,7,8 & 9.?
In footprints for KiCad, all pads with the same pad number are connected together. You can number G, D & S as 1, 2 & 3 and then draw 5 pads with pin number 2.
Pad “numbers” in KiCad are also a combination of upto 4 letters and numbers. This is for example used in BGA’s, where pads are numbered similar to a chessboard grid. Result is that you can also use “G”, “D” & “S” as pad “numbers”.
