| Vgs(th) (Max) @ id | 4V @ 250µA |
| Rds on (Max) @ id, vgs | 6mOhm @ 40A, 10V |

With a maximum Rds(on) of 6 mOhm at Vgs = 10 V and Id = 40 A, the conduction loss at 40 A is under 10 W — manageable in the D2PAK package with the exposed tab soldered to a copper plane. Input capacitance is 2150 pF at Vds = 25 V — this is the load the gate driver sees during the Miller plateau.
The D2PAK (TO-263) surface-mount package has two leads plus the drain tab.
Yes, it is AEC-Q101 qualified and carries an Automotive grade designation.
This is the spec to use for worst-case conduction loss calculations in a 12 V automotive load circuit.
