1. Zener voltage range equals nominal Zener voltage. +5% for “A” Suffix. No Suffix denotes +10%. Zener voltage is
2. read using a pulse measurement, 10 milliseconds maximum. "C" suffix = +2% and "D" suffix = +1%.
3. Zener impedance is derived by superimposing on l
ZT
a 60Hz rms AC current equal to 10% of I
ZT
.
