100 V, 75 A, 10 mOhm — the selection mistake this part avoids
This is a through-hole TO-220AB device, so the thermal path goes through the tab to a heatsink, not a PCB pad.
What the 10 mOhm Rds(on) means for your power budget
At 25 A drain current, the 10 mOhm maximum on-resistance produces 6.25 W of conduction loss — manageable with a modest heatsink in a TO-220 package. The gate charge is 80 nC at 10 V, so the gate driver needs to source about 8 nC per volt of gate swing; a standard 1 A gate driver will switch this FET in the tens of nanoseconds.
ROHS3 compliant per the listing.
