Answer Posted / jackkkk
In silicon diodes up to about 5.6 volts, the Zener effect is
the predominant effect and shows a marked negative
temperature coefficient. Above 5.6 volts, the avalanche
effect becomes predominant and exhibits a positive
temperature coefficient.
In a 5.6 V diode, the two effects occur together and their
temperature coefficients neatly cancel each other out, thus
the 5.6 V diode is the component of choice in
temperature-critical applications
