| Rds on (Max) @ id, vgs | 4.4mOhm @ 87A, 10V |

The 4.4 mOhm Rds(on) at 10 V gate drive sets the conduction-loss floor for high-current switching — at 87 A the voltage drop across the channel is under 0.4 V, which keeps the dissipation manageable even in a TO-263-7 package.
The 8000 pF input capacitance at 75 V drain-source means the gate driver must source enough peak current to hit the target rise time — a 2 A driver will slew the gate in about 50 ns.
ROHS3 compliant per Infineon's declaration.
Yes, it is ROHS3 compliant per Infineon's declaration.
Yes. With a 150 V drain-source voltage rating, the part has more than 3× headroom above a nominal 48 V bus, even accounting for transients. The 174 A continuous current and 4.4 mOhm Rds(on) make it suitable for high-current 48 V switching applications like DC-DC converters and motor drives.
