650 V, 10 A switch for offline power stages
The STD13N65M2: Rated power dissipation is 110 W at the case, but the real limit is set by the board's thermal resistance; a 1-inch-square copper pad on a 2-layer board typically derates to 2–3 W continuous without forced air.
Gate charge and switching-loss budget
The ±25 V maximum gate-source rating provides margin against ringing on the gate node in hard-switching topologies like flyback or PFC.
