Texas Instruments “TI” recently announced FemtoFET series.
There are N-channel MOSFETS like CSD15380F3 and P-channel MOSFETS like CSD25480F3 and CSD23280F3 in this series. These transistors are SMD (Surface Mount Devices) available in a very small package, the land grid array (LGA) package.
To explore this family we will highlight the FemotoFET MOSFET CSD15380F3. It has a 20V Vds, 990 mohm Rds @ Vgs=8, 500mA maximum Id, 0.5W power dissipation and ultra-small LGA Footprint 0.73 mm × 0.64 mm which make it suitable for many handheld and mobile applications.
The new MOSFET has Qg = 0.216 nC Ultra-low capacitance and that improves switching speeds in data line applications.
