Through-hole full-pack — no extra isolation hardware
That saves assembly time and one BOM line in through-hole power stages.
470 mOhm on-resistance and 19 nC gate charge
That conduction loss at 4.5 A is under 10 W — the 25 W package limit at Tc gives headroom for a 70–80 °C case temperature in a ventilated enclosure. Gate charge totals 19 nC at 10 V. Input capacitance is 547 pF at 50 V drain-source. That keeps the Miller plateau narrow and the switching edges clean enough for most offline converters without aggressive gate resistors.
