| Case | TO-252-3, DPak (2 Leads + Tab), SC-63 |
| Vgs(th) (Max) @ id | 2.5V @ 250µA |
| Rds on (Max) @ id, vgs | 33mOhm @ 5A, 10V |

The drive voltage range spans 4.5 V to 10 V, so the part can be driven from a 5 V logic-level gate signal, though the Rds(on) will be higher at the lower drive voltage — budget accordingly if your gate driver rail is 5 V or less. Gate charge is 3.7 nC at 4.5 V, which keeps switching losses low in moderate-frequency applications like solenoid drivers, relay pre-drivers, or low-side switched loads.
Yes, the STD19N3LLH6AG is listed as obsolete by STMicroelectronics. For new designs, evaluate current STripFET™ automotive N-channel MOSFETs in DPAK with comparable voltage and current ratings.
Yes, the STD19N3LLH6AG is AEC-Q101 qualified, confirming it meets automotive-grade reliability requirements for under-hood and engine-bay applications.
