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