The STL105DN4LF7AG is an STMicroelectronics AEC-Q101 qualified dual N-channel 40V STripFET™ F7 Power MOSFET in a PowerFLAT 5×6 double island package with wettable flanks. Featuring 3.5mΩ typical RDS(on) at 10V, 40A continuous drain current per die, 27.5nC gate charge, and low Crss/Ciss ratio for EMI immunity, it delivers among the lowest on-resistance in its class. The double island construction provides electrical isolation between the two MOSFETs, enabling compact half-bridge layouts for automotive motor drive, switching power supply, and load switch applications.

The STL105DN4LF7AG integrates two independent N-channel enhancement-mode MOSFETs in a single PowerFLAT 5×6 double island package. Each MOSFET uses STripFET™ F7 technology with an enhanced trench gate structure that minimizes cell pitch and optimizes the gate-drain charge (Qgd=6.1nC), resulting in very low RDS(on) of 3.5mΩ and fast switching with 11ns turn-on and 48.5ns turn-off delay. The double island construction physically separates the two MOSFET dice on separate copper islands within the package, providing electrical isolation and reducing crosstalk between high-side and low-side switches in half-bridge configurations. The wettable flank design ensures reliable solder joint inspection via automated optical inspection (AOI) systems. At VGS=4.5V, the RDS(on) increases to 8mΩ max, allowing direct drive from 3.3V/5V logic when needed.
