  • These devices are N-channel Power MOSFETs based on the MDmesh™ M5 innovative vertical process technology combined with the well-known PowerMESH™ horizontal layout. The resulting products offer extremely low on-resistance, making them particularly suitable for applications requiring high power and superior efficiency.

    Key Features

    • Extremely low RDS(on)
    • Low gate charge and input capacitance
    • Excellent switching performance
    • 100% avalanche tested
