The type numbers shown have a standard tolerance of
±5%
on the nominal zener voltage, C for
±2%,
D
Maximum zener current ratings(I
ZM
):
Maximum zener current ratings are based on maximum zener voltage of the individual units and JEDEC
250 mW rating.
3)
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 100μA and V
Z
at 10μA.
