b) The temperature coefficient of the reference voltage SZ is a function of IZ. Reference diodes are classified at the
specified test current, and the SZ of the reference diode will be different at different levels of IZ. The absolute value
of IZ 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 the stability of IZ on SZ is shown in Fig.2.
