400V, 3A N-Channel — the SuperMESH power switch for offline supplies
It comes in a TO-251 (IPAK) through-hole package — a compact three-lead footprint that suits automated insertion or hand-soldering in low-to-medium power offline converters, auxiliary supplies, and lighting ballasts.
1.8 Ohm Rds(on) — conduction loss at the switching node
Maximum on-resistance is 1.8 Ohm at 1.5 A drain current with 10 V gate drive.
Through-hole TO-251 — board-mounting and thermal path
The TO-251 (IPAK) package has three short leads and a metal tab that carries the drain. The through-hole leads provide mechanical strength for point-of-load regulators or modules that see vibration.
