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 lZTA 60Hz rms a.c. current

equal to 10% of lZT.
