NOTE 2
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%.
Zener impedance is derived by superimposing on lZT a 60Hz rms ac current equal to 10 % of IZT.
