Product details

2.4 mOhm Rds(on) at 90 A — the conduction-loss floor for a 40 V rail

The IRFR7440TRPBF: The 140 W power dissipation rating at case temperature tells you the package can sink significant heat, but the board layout — the exposed pad area and via count under the tab — will set the real thermal impedance.

Gate charge and switching — what 134 nC means for the driver

The total gate charge of 134 nC at 10 V is the energy the gate driver must deliver per switching cycle. Input capacitance is 4610 pF at 25 V Vds.

Temperature grade and application envelope

The gate threshold voltage maximum is 3.9 V at 100 µA drain current. With a 6 V to 10 V drive range for minimum Rds(on), a 5 V logic-level gate signal will not fully enhance the channel — you need a 10 V rail or a dedicated gate-driver IC to hit the 2.4 mOhm spec.
