I want to use small SMD LED in my PCB just for indication purposes (Rx/Tx pins, power rail). I have found this one; I think it will do the job. However, the footprint is obscure
You might end up with a power LED that has a third pin, electrically isolated from anode and cathode, just for removing heat.
I can't get it from the datasheet... Should I make third pad or it is simply designator? Will I end up fine with a two simple rectangular pads?
Thanks in advance.
