Product details

40 V Vdss — the voltage ceiling that limits 48 V use

The 40 V drain-to-source rating is the hard voltage limit. A 48 V nominal bus (like telecom or industrial 48 V systems) exceeds this rating even at steady state, let alone during transients. This part is sized for 12 V, 24 V, or 36 V rails where the maximum peak stays under 40 V. For 48 V applications, look for a 60 V or 75 V rated MOSFET in the same D2PAK footprint.

Obsolete — sourcing from surplus and broker channels

Sourcing now runs through independent distribution and surplus stock.

3.7 mOhm Rds(on) — what it means for thermal design

Package and temperature range — D2PAK for surface-mount power

The D2PAK (TO-263-3) surface-mount package with exposed tab allows the PCB copper to act as a heatsink.

Frequently asked questions

What is the Rds(on) of IRF1404ZSTRL?

The maximum on-resistance is 3.7 mOhm at 75 A drain current and 10 V gate drive. This is the figure used for conduction loss calculations in high-current switching designs.

Can I use IRF1404ZSTRL in 48V systems?

No. The 40 V drain-to-source rating is below the 48 V nominal bus voltage. Use a 60 V or 75 V rated MOSFET for 48 V applications.

What is the replacement for IRF1404ZSTRL?

No official replacement is listed in the manufacturer's records. For a similar low-voltage, high-current N-channel MOSFET in D2PAK, consider parts with 40 V or higher Vdss and comparable Rds(on) from the same HEXFET family or competitors. The exact substitute depends on your gate drive voltage and switching frequency requirements.
