Tolerance and voltage designation(Vz):
The type numbers shown have a standard tolerance of
±5%
on the nominal zener voltage, C for
±2%,
D
for
±1%.
2)
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.
