600 V N-channel with 1.5 Ohm Rds(on) — the low-power offline switch
Gate charge is 9.4 nC at 10 V, and input capacitance sits at 200 pF at 100 V drain bias — a light load on the gate driver, which keeps the drive-stage BOM lean in space-constrained designs.
Through-hole TO-251 — fit for manual assembly and vibration
The PG-TO251-3 package (IPak variant with short leads) is a through-hole footprint that suits wave-solder or hand-solder assembly. The three leads drop into a 2.54 mm pitch hole pattern, and the tab is soldered to the board pad for thermal management — the device is rated for 49 W power dissipation at the case. The maximum gate-source voltage is ±20 V, so standard 10–15 V gate drive rails are safe.
