1)
The type numbers shown above have a standard tolerance of ±5% on the nominal Zener voltage. Also available in 2%
and 1% tolerance, suffix C and D respectively. V
Z
is measured with the diode in thermal equilibrium in 25
O
C still air.
2)
Zener impedance is derived by superimposing on I
ZT
, a 60 Hz rms a.c. current equal to 10% of I
ZT
(25
μA
a.c.).
3)
Tested with pulses tp = 20 ms.

Noise density, (N
D
) is specified in microvolts-rms per square-root-hertz.
Actual measurement is performed using a 1KHz to 8KHz frequency
bandpass filter at a constant Zener test current(I
ZT
) at 25 C ambient
temperature. N
D
is calculated from the formula.
