NOTE 1
Zener voltage range equals
“nominal Zener voltage”
(see table) + 5%, for “B”
Suffix types. “A” Suffix denotes +
10%. No Suffix denotes + 20%.
"C" suffix = + 2% tolerance and
"D" suffix = + 1% tolerance.
NOTE 2
Zener impedance is derived by
superimposing on lZTA 60 Hz rms
a.c. current equal to 10% of lZT
NOTE 3
Zener voltage is read using a
pulse measment, 10 miliseconds
maximum.
