TYPICAL CHANGE OF TEMPERATURE COEFFICIENT
WITH CHANGE IN OPERATING CURRENT.
TYPICAL CHANGE OF ZENER VOLTAGE
WITH CHANGE IN OPERATING CURRENT
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.
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%/
C. To obtain the
typical Temperature Coefficient limits for this same diode operated at a current of
6.0mA, the new TC limits (%/
C) 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%.
C. The algebraic sum of +/-0.005%
C and –
0.0006%/
C gives the new estimated limits of +0.0044%/oC and -0.0056%/oC.
