Product overview

Description

These very high voltage N-channel Power MOSFETs are designed using MDmesh K5 technology based on an innovative proprietary vertical structure. The result is a dramatic reduction in on-resistance and ultra-low gate charge for applications requiring superior power density and high efficiency.

  • All features

    • Very low FoM (figure of merit)
    • Ultra-low gate charge
    • 100% avalanche tested
    • Zener-protected
