Product details

The STMicroelectronics STD95N4LF3 is a 40 V, 80 A N-channel power MOSFET built on the STripFET™ III process. It is designed for high-efficiency switching in DC-DC converters, motor drives, and load switches where low conduction loss matters.

Ratings that drive the BOM decision

The 80 A continuous drain rating at 25 °C case temperature sets the raw current capability, but the 110 W power dissipation limit and the DPAK package's thermal resistance define how much current you can actually pull in your board's airflow or heatsink arrangement.

The supplier device package is DPAK, identical to the case code.
