    V max = Maximum operating voltage device can withstand without damage at rated current (Imax).
    I max = Maximum fault current device can withstand without damage at rated voltage (V max).
    I hold = Hold Current. Maximum current device will not trip in 25°C still air.
    I trip = Trip Current. Minimum current at which the device will always trip in 25°C still air.
    Pd = Power dissipation when device is in the tripped state in 25°C still air environment at rated voltage.
    Ri min/max = Minimum/Maximum device resistance prior to tripping at 25°C.
    R1max = Maximum device resistance is measured one hour post reflow.
    CAUTION : Operation beyond the specified ratings may result in damage and possible arcing and flame.
