DESCRIPTION

APPEARANCE

The 1N821UR thru 1N829AUR-1 series of surface mount 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

surface mount DO-213AA (MELF) reference diodes are optionally available

with an internal-metallurgical-bond by adding a “-1” suffix. This type of

bonded Zener package construction is also available in JAN, JANTX, and

JANTXV military qualifications. Microsemi also offers numerous other

Zener Reference Diode products for a variety of other voltages up to 200 V.

DO-213AA

NOTES:

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

of 6.15 V, add a further hyphened suffix number % to the part number for desired tolerance, e.g. 1N827UR-1-2%, 1N829UR-1-1%,

1N829AUR-1%, 1N829AUR-1-1%, etc.

Zener impedance is measured by superimposing 0.75 mA ac rms on 7.5 mA dc @ 25^oC.

The maximum allowable change observed over the entire temperature range i.e., the diode voltage will not exceed the specified mV

change at any discrete temperature between the established limits.

Voltage measurements to be performed 15 seconds after application of dc current.

1N821UR-1, 1N823UR-1, 1N825UR-1, 1N827UR-1, and 1N829UR-1 also have qualification to MIL-PRF-19500/159 by adding the JAN,

JANTX, or JANTXV prefix to part numbers as well as the “-1” suffix; e.g. JANTX1N827UR-1, JANTXV1N829UR-1, etc.

This product series has also been previously identified as the MLL821 thru MLL829A-1. This alternate name may still be used.

TYPICAL CHANGE OF ZENER VOLTAGE

WITH CHANGE IN OPERATING CURRENT

The curve shown in Figure 2 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 2.

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 new estimated limits of +0.0044%/oC and -0.0056%/oC.

This curve in Figure 3 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 2, this curve can be used to

estimate total voltage regulation under conditions of both

varying temperature and current.
