I am assembling a board which uses some IRFD110 MOSFETs but I don't know which way round to insert them. The PCB shows the components with a semi-circular cutout on one end, like many components, but the component itself has no such indicator. The MOSFETs are 4-pin devices with 2 pins linked, but that is not indicated on the PCB. How do I determine which way to orientate the MOSFETs?
