100 V, 80 A N-channel HEXFET in D2PAK
It comes in a D2PAK (TO-263) surface-mount package, designed for high-current switching applications where board space is tight but thermal performance still matters — the large copper tab on the D2PAK pulls heat into the PCB plane.
15 mOhm Rds(on) — what it means for conduction loss
At 45 A, that works out to roughly 30 W conduction loss at the hot junction — the 260 W package dissipation rating (at case temperature) gives enough thermal headroom for a properly heatsunk design, but the junction temperature derating curve is the real limiter in continuous operation.
Gate charge and switching drive
That makes it suitable for under-hood automotive, industrial motor drives, telecom rectifiers, and battery management systems where the ambient can push past 85°C and the MOSFET sees self-heating on top.
It is ROHS3 compliant, and the D2PAK package is a standard surface-mount format that remains widely used in power designs.
