CDIDI CD751A, CD750A, CD759A, CD758A, CD757A Datasheet
...
NOTE 1 Zener voltage range equals nominal voltage +5% for “A” Suffix types. No Suffix denotes + 10%.
"C" suffix = +
2% and "D" suffix = + 1%.
NOTE 2 Zener voltage is read using a pulse measurement, 10 milliseconds maximum.
NOTE 3 Zener impedance is derived by superimposing on 1
ZT
A 60Hz rms a.c. current equal
to 10% of 1ZT.
MAXIMUM RATINGS
