| Case | TO-220-3 |
| Vgs(th) (Max) @ id | 1.7V @ 250µA |
| Rds on (Max) @ id, vgs | 18mOhm @ 27.5A, 10V |
| Gate charge (Qg) (Max) @ vgs | 37 nC @ 4.5 V |

The Rds(on) of 18 mOhm at 27.5 A and 10 V is the number you check first on a failed board — if the original FET ran hot and the replacement has higher on-resistance, the same load current will push the junction past the 95 W dissipation limit.
