Product details

That conduction loss stays under 0.65 W at 40 A RMS in a typical 12 V rail, which means the heatsink can be small or the PCB copper does the work. But the 200 nC total gate charge at 10 V means the gate driver needs to source and sink that charge fast — a 1 A driver gives roughly 200 ns rise time, acceptable for 50–100 kHz switching; above that, budget a stronger driver or accept higher crossover loss.

D2PAK package — rework and thermal reality

Under a hot-air station, the large tab soaks heat quickly; preheat the board to 125°C before rework, or the solder on the tab reflows before the leads wet, trapping voids.

For dual-sourcing or a drop-in alternative, the IRF1404ZPBF is a common cross-shop candidate — same 40 V, 162 A rating in the same D2PAK footprint, but with Zener-gate protection that slightly raises the gate threshold. Check the gate drive voltage against your circuit before swapping.

Frequently asked questions

What is the maximum gate charge of the IRF1404SPBF?

The maximum gate charge is 200 nC at 10 V gate-to-source voltage, as listed in the specifications. This value drives the gate-driver sizing for switching applications.

Is the IRF1404SPBF lead-free and RoHS compliant?

The 'PBF' suffix in the order code indicates lead-free (Pb-free) plating, and the part is RoHS compliant per Infineon's standard environmental compliance. No separate certification number is carried in this listing.
