800V MDmesh K6 super-junction power MOSFET in a TO-220 package

stp80n240k6 super junction power mosfet

Recommended for flyback topology-based applications such as LED lighting, chargers and adapters, MDmesh K6 power MOSFETs reduce both BOM cost and board size thanks to their increased power density

This very-high-voltage N-channel Power MOSFET is designed using the latest MDmesh K6 technology based on ST's 20 years' experience with super-junction technology. The result is the best-in-class on-resistance per area and gate charge for applications requiring superior power density and high efficiency.

Key features

  • World's best RDS(on) x area
  • World's best FOM (figure of merit)
  • Ultra-low gate charge
  • 100% avalanche tested
  • Zener-protected
