I'm trying to create a symbol that consists of multiple other symbols. I'd like it to look similar to what's in this datasheet.

I have found out how to create the part itself, but i'm not sure if I can use the MOSFET symbols combined with diode symbols to create the symbol for this part. Any assistance is greatly appreciated.

Several things:

  • there's a package and there's a symbol. Package exists to connect pads on the board with conductive tracks, symbol on schematic exists to present, in human readable format, the sense of the connections. I saw many times people using package-like symbols on schematics, and it is not a right way - it creates messy circuit diagrams which are hard to read. My advice: do not draw symbol as it is shown in this datasheet;
  • then, you can see there're two identical functionally independent pieces in this package. You should create a symbol for one of them, and then, at device level, add two of them to the device, and then assign package and pins to pads of the symbol;
  • there's a trick. I am sure there's LED symbol already existing in DIODE library, and I am sure there's MOSFET existing in some other library. You do not need to reinvent bicycle, your task is to copy-paste their symbols into newly created symbol, and ensure pins are named properly, and symbol in overall looks properly and is human-readable.
