NOTE 1 Zener voltage range equals nominal voltage + 5% for “B” Suffix. “A” Suffix denotes + 10%,
No Suffix denotes + 20%, "C" suffix denotes + 2%, "D" suffix denotes + 1%.
NOTE 2 Zener voltage is read using a pulse measurement, 10 milliseconds maximum.
NOTE 3 Zener impedance is derived by superimposing on 1ZT A 60Hz rms a.c. current equal
to 10% of 1ZT
