The 600 V drain-source voltage gives you headroom for universal-input (85–265 VAC) offline converters with derating for ringing on the drain node. The 280 mOhm Rds(on) at 10 V gate drive sets the conduction loss — at 6.5 A you are looking at roughly 12 W dissipation in the channel alone, which the 32 W package limit can handle with a good heatsink. Gate charge is 43 nC at 10 V, so the driver sees a moderate capacitive load; a standard 1 A gate-driver IC will switch it cleanly in the 50–100 kHz range. Input capacitance of 950 pF at 100 V Vds keeps the Miller plateau manageable.
Infineon lists the IPAW60R280CEXKSA1 as obsolete. For BOM lines that already specify this part, the supply path runs through independent distribution — surplus inventory, last-time-buy stock, or broker-sourced material.
