Product details

Gate charge and input capacitance — what the driver sees

The IRF1404LPBF: With 200 nC typical gate charge at 10V and 7360 pF input capacitance at 25V drain, this FET demands a gate driver capable of sourcing and sinking several amps to switch the channel in the tens of nanoseconds — a standard logic-level output will not turn it on fast enough, so plan for a dedicated driver stage.

Through-hole TO-262 — board integration

The TO-262-3 (I²Pak) package with long leads mounts through a PCB hole and accepts a heatsink clip or screw — the 200W power dissipation at case temperature assumes a thermal interface to a heatsink, not free-air convection.

Frequently asked questions

What is the IRF1404LPBF's gate charge and what does it mean for driver selection?

The typical gate charge is 200 nC at 10V, with an input capacitance of 7360 pF at 25V drain. This means a standard logic output cannot drive it directly — a gate driver capable of delivering several amps peak is needed to achieve fast switching edges.
