STF12N120K5:N-channel 1200 V, 0.62 Ohm typ., 12 A MDmesh K5 Power MOSFET in TO-220FP package

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.

Key Features

  • Industry’s lowest RDS(on) x area
  • Industry’s best figure of merit (FoM)
  • Ultra low gate charge
  • 100% avalanche tested
  • Zener-protected
