| Case | 8-PowerTDFN |
| Vgs(th) (Max) @ id | 3.4V @ 10µA |
| Rds on (Max) @ id, vgs | 8.4mOhm @ 20A, 10V |
| Gate charge (Qg) (Max) @ vgs | 13.7 nC @ 10 V |

The drive voltage range is specified for 7 V (minimum Rds(on)) and 10 V (maximum Rds(on)), so a 10 V gate rail is the recommended drive level to achieve the rated on-resistance. The 771 pF input capacitance at 25 V drain-source helps estimate the switching speed and driver current requirement.
Yes. The 40 V drain-source rating provides margin on 12 V and 24 V automotive buses.
The order code IPZ40N04S58R4ATMA1 is the standard suffix variant of the base part number IPZ40N04S58R4. The ATMA1 suffix indicates the specific packaging and reel configuration. No functional difference is expected, but confirm the package code and reel quantity against your BOM before substituting.
