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