Product details

30 V, 2.8 mΩ — what this MOSFET delivers in a switching design

Gate charge is 29 nC at 4.5 V, which means the driver doesn't need to push much current to turn the device on and off — switching losses stay manageable even at moderate frequencies. Continuous drain current is rated 80 A at the case temperature 25°C, but that number is package-limited; real-world current depends on PCB copper and airflow.

Obsolete — sourcing the STD150N3LLH6 today

STMicroelectronics lists the STD150N3LLH6 as obsolete. Any stock in the channel is what remains from the final production runs — franchised distributors may show zero inventory, and the part moves through independent surplus and broker networks.

The 2.8 mΩ Rds(on) at 10 V drive is the figure that determines I²R loss in a continuous-duty switch or the bottom FET of a synchronous converter. At 40 A, that's about 4.5 W of dissipation in the die alone — the DPAK's thermal pad and board copper must pull that heat away.

Frequently asked questions

Is STD150N3LLH6 obsolete?

Yes, STMicroelectronics has marked the STD150N3LLH6 as obsolete. No further production is planned. Stock is limited to existing inventory in the distribution channel.
