Gate charge and switching loss budget
The IPP60R160P6XKSA1: Total gate charge is 44 nC at 10 V, and input capacitance measures 2080 pF at 100 V drain-source.
Thermal and voltage headroom for offline supplies
The 600 V drain-source rating covers universal AC input with margin for reflected voltage and leakage spikes in a single-switch flyback or PFC stage. Maximum power dissipation is 176 W at case temperature, but the junction range extends from -55°C to 150°C.
