This part is two AO3400 gates in one physical package.
The standard KiCad library does not have a schematic symbol for this part, although the footprint is a SOT-23-6. Is it more correct to draw one mosfet, then specify the footprint contains two instances or two mosfets side-by-side ? The two are independent and have no common connections. When drawing it as one mosfet (with two instances) part placement appears to drop an A followed by a B (for the two halves). It feels a bit existential, but one approach is probably more correct than the other.
