*JEDEC Registered Data.

†Double Anode; electrical specifications apply under both bias polarities.

NOTES:

1.

6.35 V, add a hyphened suffix to the part number for desired tolerance, e.g. 1N827-1-2%, 1N829-1-1%, 1N829A-1%, 1N829A-1-1%, etc.

2.

Zener impedance measured by superimposing 0.75 mA ac rms on 7.5 mA dc @ 25

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.

1N821, 1N823, 1N825, 1N827, and 1N829 also have qualification to MIL-PRF-19500/159 by adding the JAN,

JANTX, JANTXV, or

JANS prefix to part numbers as well as the “-1” suffix; e.g. JANTX1N827-1, JANTXV1N829-1, etc.

6.

Designate Radiation Hardened devices with “RH” prefix instead of “1N”, e.g. RH829A instead of 1N829A.

FIGURE 1

TYPICAL CHANGE OF TEMPERATURE COEFFICIENT

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%/

limits for this same diode operated at a current of 6.0mA, the

new TC limits (%/

FIGURE 1.

At a test current of 6.0mA the change in Temperature Coefficient

(TC) is approximately –0.0006%.
