NOTE 1
NOTE 2
NOTE 3
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.
Zener impedance is derived by superimposing on lZTA 60 Hz rms ac current equal to
250
μA
.
Zener voltage is read using a pulse measurement, 10 milliseconds maximum.
