Sales Briefcase
  • The MDmesh™ is a new revolutionary Power MOSFET technology that associates the multiple drain process with the company’s PowerMESH™ horizontal layout. The resulting product has an outstanding low on-resistance, impressively high dv/dt and excellent avalanche characteristics. The adoption of the Company’s proprietary strip technique yields overall dynamic performance that is significantly better than that of similar competition’s products.

    Key Features

    • High dv/dt and avalanche capabilities
    • 100% avalanche tested
    • Low input capacitance and gate charge
    • Tight process control and high manufacturing yields
    • Low gate input resistance
