Does the Current Flow Backwards Inside a Battery?
Note that in metals, the current is conducted by electrons, but by definition, in the opposite direction to the electric current. In other materials, charge carriers can be negative or positive. By convention, the current is always assumed to flow in the direction of positive charge, disregarding the material and mechanism for its conduction.

But the datasheet table 8, provides the value for a reverse zener current of 5mA only. But they didn''t mention whether it is the minimum or the maximum zener current. As Tony Stewart answered, 5 mA is neither. Maximum current is set by the power dissipation of the zener. In this case it''s 250 mW, which implies a current of just about 20 mA (20 mA times 12 …
