The FS70KMJ-2 is an N-channel MOSFET rated for 70 A continuous drain current and 100 V drain-source voltage. That current rating puts it in the high-current switching tier — think motor drives, battery isolation, DC-DC converter output stages, and heavy-load hot-swap controllers where the steady-state current through the FET is tens of amps and the bus voltage stays under 80 V with derating.
Bulk shipping means the parts arrive loose in a bag or tube — if your pick-and-place line expects tape-and-reel, factor in a hand-load or tray-feed step.
