  • This n-channel enhancement mode Power MOSFET is the latest refinement of STMicroelectronics unique “single feature size™” strip-based process with less critical alignment steps and therefore a remarkable manufacturing reproducibility. The resulting transistor shows extremely high packing density for low on resistance, rugged avalanche characteristics and low gate charge.

    Key Features

    • Ultra low on-resistance
    • 100% avalanche tested
