The SPP03N60S5: The 600 V drain-source rating gives 2× derating on a 230 VAC rectified bus (≈325 VDC) and comfortable margin for universal-input flyback or PFC stages. Continuous drain current is 3.2 A at 25°C case temperature, defining the load budget for a 20–50 W switching supply. The 1.4 Ohm Rds(on) at 10 V gate drive is moderate for this voltage class. The 16 nC total gate charge is low versus older planar 600 V parts.

Through-hole TO-220-3 (PG-TO220-3-1). The tab is the drain. With 38 W maximum power dissipation at the case, a TO-220 bolted to a modest heatsink keeps junction temperature in check.
