Description

    These N-Channel enhancement mode power FQA38N40 field effect transistors are produced using Fairchild's proprietary, planar, DMOS technology.
    This advanced technology FQA38N40 has been especially tailored to minimize on-state resistance, provide superior switching performance, and withstand high energy pulse in the avalanche and commutation mode. FQA38N40 is well suited for high efficiency switching DC/DC converters and switch mode power supplies.
