    I understand there is 3 components of reverse current in a diode.

    1. Transient
    2. Minority-Carrier (saturation current)
    3. Surface Leakage

    The question I am trying to solve asks for the values of surface leakage current and the saturation current at 25 deg C.

    It gives the information that the diode has a reverse current of 5uA at 25 deg C and a reverse current at 100uA at 100 deg C.

    What do they mean when they say reverse current? Is the "reverse current" the 1. transient current or 2. saturation current or 3. surface leakage current?

    Is the value of reverse current all three of these added up? or is reverse current value the same as just one of these three types?

    Thanks

    The reverse current in the specs will be a measured value*. In addition to this it will be a steady-state value (so it will exclude any current required to charge the junction capacitance).

    *More likely it will be a statistical estimate of the limit(s) of the range of values which might be measured.
