Notes:
1. The Zener Volta
g
e
(
V
Z
)
is tested under
p
ulse condition of 10ms.
2. The device numbers listed have a standard tolerance on the nominal zener volta
g
e of ±5
%
.
4. The zener impedance is derived from the 60-cycle ac voltage, which results when an ac current having an rms value
equal to 10% of the DC zener current (IZT or IZK) is superimposed to IZT or IZK.
