The quoted values of AVref are based on a constant current 17. Two factors can cause Vref to change, namely the differential resistance r^jff and the temperature coefficient Sz- a. As the max. rjjff of the device can be 50 J2, a change of 0,01 mA in the current through the reference diode will result in a AVref of 0,01 mA x 50 ft = 0,5 mV. This level of AVref is not significant on a BZV10 (AVref < 46 mV), it is however very significant on a BZV14 (AVref<2,3mV). b. The temperature coefficient of the reference voltage Sz is a function of 12- Reference diodes are classified at the specified test current and the Sz of the reference diode will be different at the different levels of Ijj. The absolute value of \\2 is important, however, the stability of Iz, once the level has been set, is far more significant. This applies particularly to the BZV13 and BZV14. The effect of Iz stability on Sz is shown in Fig. 3. Voltage excursion (AVref and temperature coefficient). All reference diodes are characterized by the 'box method'. This guarantees a maximum voltage excursion (AVref) over the specified temperature range, at the specified test current (Iz), verified by tests at indicated temperature points within the range. Vz is measured and recorded at each temperature specified. The AVref between the highest and lowest values must not exceed the maximum AVref given. The temperature coefficient, therefore is given only as a reference; but may be derived from: 'vref 1-Vref 2>* 100 <Tamb2 - Tamb1> x vref nom %/K. Quality Semi-Conductors
