*JEDEC Registered Data.
Double Anode; electrical specifications apply under both bias polarities.
NOTES:
1.
When ordering devices with tighter tolerances than specified, use a nominal VZ voltage of 6.2V.
2.
Zener impedance measured by superimposing 0.75 mA ac rms on 7.5 mA dc @ 25
oC.
3.
The maximum allowable change observed over the entire temperature range i.e., the diode voltage will not exceed the
specified mV change at discrete temperature between the established limits.
4.
Voltage measurements to be performed 15 seconds after application of dc current.
5.
Designate Radiation Hardened devices with “RH” prefix instead of “1N”, i.e., RH829A instead of 1N829A.

FIGURE 1
The curve shown in Figure 1 is typical of the diode series and
greatly simplifies the estimation of the Temperature Coefficient
(TC) when the diode is operated at currents other than 7.5mA.
EXAMPLE: A diode in this series is operated at a current of
7.5mA and has specified Temperature Coefficient (TC) limits of
+/-0.005%/
oC. To obtain the typical Temperature Coefficient
limits for this same diode operated at a current of 6.0mA, the
new TC limits (%/
oC) can be estimated using the graph in
FIGURE 1.
At a test current of 6.0mA the change in Temperature Coefficient
(TC) is approximately –0.0006%.
oC. The algebraic sum of +/-
0.005%
oC and –0.0006%/oC gives the estimated limits of
+0.0044%/
oC and -0.0056%/oC.
