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