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.

DO-7

(DO-204AA)

NOTES:

1. Add a “-1” suffix for internal metallurgical bond. When ordering devices with tighter tolerances than specified for the V_Zvoltage nominal of

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^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. 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.

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.
