NOTE 3.
Z
These graphs can be used to determine the maximum voltage change of any device in the
series over any specific temperature range. For example, a temperature change from 0 to
+50°C will cause a voltage change no greater than +31 mV or – 31 mV for 1N821 or 1N821A,
as illustrated by the dashed lines in Figure 1. The boundaries given are maximum values. For
greater resolution, an expanded view of the center area in Figure 1a is shown in Figure 1b.

age variation (∆V ) over the specified temperature range, at the specified test current (I ),

ZT
verified by tests at indicated temperature points within the range. V is measured and re-
Z
corded at each temperature specified. The ∆V between the highest and lowest values must
not exceed the maximum ∆V given. This method of indicating voltage stability is now used
Z
Z
for JEDEC registration as well as for military qualification. The former method of indicating
voltage stability — by means of temperature coefficient accurately reflects the voltage devi-
ation at the temperature extremes, but is not necessarily accurate within the temperature
rangebecausereferencediodeshaveanonlineartemperaturerelationship. Thetemperature
coefficient, therefore, is given only as a reference.
NOTE 4.
The maximum voltage change, ∆V , Figures 2 and 3 is due entirely to the impedance of the
device. If both temperature and I are varied, then the total voltage change may be obtained
by graphically adding ∆V inFigure2or3tothe∆V inFigure1forthedeviceunderconsider-

ation. If the device is to be operated at some stable current other than the specified test cur-
rent, a new set of characteristics may be plotted by superimposing the data in Figure 2 or 3
on Figure 1. For a more detailed explanation see application note in later section.
NOTE 2.
The dynamic zener impedance, Z , is derived from the 60 Hz ac voltage drop which results
