Sourcing and lifecycle — still a current-production part
The N0436N-ZK-E1-AY: ROHS3 compliant. For BOM planning, that means no urgent need to qualify a substitute — though having a second-source candidate in the same TO-252 footprint is always good practice for supply resilience.
Package and mounting — hand-solderable with care
The TO-252-3 (DPak) is a common surface-mount power package with a tab that carries the drain. It reflows well and can be hand-soldered if you have a hot-air station or a large-tip iron — the tab needs good thermal contact to the PCB copper pour for heat spreading. The 1 W dissipation in still air (Ta) jumps to 87.4 W when the case is held at 25°C, so the board layout and heatsinking decide how much current you can actually pull.
