The IRF1404ZSTRRPBF: Housed in a D2Pak (TO-263-3) surface-mount package, this part dissipates up to 200 W case-limited.
Date-code provenance matters here — verify the stock comes from a traceable channel to avoid counterfeit risk on an EOL part.
The 40 V Vdss gives 50% derating margin on a 12 V rail and comfortable headroom on a 24 V system, but for 48 V bus architectures this part is too close to the limit — look for a 60 V or 75 V rated MOSFET instead. The 180 A continuous rating is a package-limited number at 25°C case temperature; real-world current depends on heatsinking and ambient. The 3.7 mOhm Rds(on) at 10 V drive means the gate must see a full 10 V to achieve the lowest on-resistance — a 5 V logic-level gate drive will roughly double the resistance, increasing conduction losses.
