The 55 V Vdss gives comfortable headroom on 12 V and 24 V rails, but it is tight for 48 V systems — budget derating if you push past 40 V steady-state. The 80 A continuous drain is rated at case temperature 25°C; real-world current is derated by the 300 W power dissipation ceiling and the thermal resistance of your heatsink. Gate charge is 142 nC at 10 V, so your gate driver needs to source and sink that charge quickly to avoid slow switching edges and extra dissipation.
Through-hole TO-220. Gate threshold 4 V max at 250 µA. Junction temperature -55°C to 175°C.
