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.

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.

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.

In conjunction with Figure 2, this curve can be used to

estimate total voltage regulation under conditions of both

varying temperature and current.
