N-Channel TrenchFET® Gen III Power MOSFETs

Vishay and Digi-Key offer one of industry's lowest on-resistances

Image of Vishay/Siliconix's N-Channel TrenchFET® Gen III Power MOSFETsVishay has expanded its family of Gen III TrenchFET power MOSFETs with the release of a new 20 V n-channel device offering the one of the industry’s lowest on-resistance and on-resistance times gate charge for a device with this voltage rating in the PowerPAK® SO-8 package type.

TrenchFET Gen III power MOSFETs are ideal for low-side applications, where their low on-resistance minimizes conduction losses and improves efficiency compared to previous-generation MOSFETs. Also lower gate charge yields approximately 1/3 lower FOM in some devices, providing lower switching losses over the previous generation.


  • Low conduction and switching losses enable increased efficiency and reduced power consumption
    • Record-breaking maximum on-resistance at VGS = 4.5 V rating is up to 32% - Down to 0.002 Ω
    • Maximum on-resistance at VGS = 10 V is also up to 23% lower - Down to 0.00155 Ω
    • Figure of Merit (FOM) of on-resistance times gate charge up to 42% lower - Down to 87 mΩ-nC
  • 20 V, 25 V, and 30 V options, all with 20 V VGS
  • Package options in SO-8 footprint area include:
    • Thermally advanced PowerPAK SO-8
    • Standard SO-8
    • PolarPAK® with double-sided cooling
