DESCRIPTION
APPEARANCE
The popular 1N821 thru 1N829 series of Zero-TC Reference Diodes
provides a selection of both 6.2 V and 6.55 V nominal voltages and
temperature coefficients to as low as 0.0005%/oC for minimal voltage
change with temperature when operated at 7.5 mA. These glass axial-
leaded DO-7 reference diodes are also available in JAN, JANTX, JANTXV,
and JANS military qualifications. Microsemi also offers numerous other
Zener Reference Diode products for a variety of other voltages up to 200 V.

*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 @ 25oC.
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.
GRAPHS
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.

This curve in Figure 2 illustrates the change of
diode voltage arising from the effect of
impedance. It is in effect an exploded view of
the zener operating region of the I-V
characteristic.
In conjunction with Figure 1, this curve can be
used to estimate total voltage regulation under
conditions of both varying temperature and
current.
