120 A, 60 V N-channel HEXFET in D2PAK
It comes in a D2PAK (TO-263-3) surface-mount package with an exposed tab for heat sinking.
3 mOhm Rds(on) — what it means for conduction loss
That translates to about 17 W conduction loss at 75 A — manageable with a decent copper area on the D2PAK tab. At 120 A the loss climbs to ~43 W, so the thermal design (copper pour, airflow, or heatsink) must match the actual load current. For a 100 kHz switching application, the average gate drive current is about 17 mA — well within a typical driver's capability.
Package and mounting — D2PAK reality
The D2PAK (TO-263-3) package has two leads plus the tab.
The ROHS3 compliance is confirmed, making it suitable for designs requiring lead-free soldering and EU RoHS conformance.
