Low RDS(on) MOSFETs in Ultra Small Packages

Check out Nexperia's extensive range of high-performance, low RDS(on) MOSFETs in very-small DFN2020 and DFN1006 packages. These products address the trends towards higher efficiency, increased power density, and lower power consumption.

The SOT23 for portables - DFN1006

  • About a factor 7 smaller than a SOT23 but delivers the same power dissipation (350 mW)
  • 2 versions: both with 1 x 0.6 mm size but different height with 0.37 mm (DFN1006B-3) and 0.5 mm (DFN1006-3)
  • Multisourcing due to a broad supplier base:
    • > 5 supplier for footprint compatible packages
    • Big portfolio range of MOSFETs and bipolar transistors available in the market
    • Broad current range of 100 mA to 1 A supported
  • These MOSFETs are a very good choice for load switches in power management units of portable devices

The 2 x 2 x 0.65 mm DFN2020 single and dual MOSFETs are most advanced in power density:

  • They take up only 4 mm2 mounting area but have similar thermal resistance as a standard SO-8
  • Optimized for switching performance and low RDS(on), this family of products is ideal for battery/charger switching and DC/DC converters in portable applications
  • The single DFN2020 package comes with tin-plated solderable side pads ("wettable flanks") for easy soldering inspection


  • P- and N-channel types from 12-60 V
  • ESD protected product types up to 3 kV HBM
  • Automotive types with AEC-Q101 qualification
  • Product types with tin-plated solderable side pads
  • Very-low RDS(on) values of less than 0.65 mOhm at 2.5 V (for DFN1006 types)
  • RDS(on) range down to 10 mOhm and ID up to 13 A (for DFN2020 types)


  • Power conversion and switching functionalities in small, thin, and battery-driven electronic devices
  • Other space-constrained applications in automotive, consumer, and industrial
