Product details

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.

Frequently asked questions

What is the replacement for IRF1404ZSTRRPBF?

No official replacement is listed by Infineon for this specific order code. For a pin-compatible alternative in the same D2Pak footprint, look at other 40 V N-channel MOSFETs in the HEXFET family with similar Rds(on) and current ratings — but verify gate drive and switching characteristics against your design. We can help identify a cross if you send the full BOM context.
