1) 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(IZM):
Maximum zener current ratings are based on maximum zener voltage of the individual units and JEDEC
250 mW rating.
