Toleranzing and voltage designation (V
Z
). The type numbers shown have a standard tolerance of ± 5 % on the nominal zener voltage.
Maximum zener current ratings (I
ZM
). Maximum zener current ratings are based on maximum zener voltage of the individual units.
Reverse leakage current (I
R
). Reverse leakage currents are guaranteed and measured at V
R
as shown on the table.
Maximum voltage change (ΔV
Z
). Voltage change is equal to the difference between V
Z
at 100 µA and V
Z
at 10 µA.
