STABILIZERS
Even if with the experiments previously described it has been demonstrated that the semiconductor diode is behaved from stabilizing element of voltage, in practical, in order to carry out this important function, reruns to one special diode , purposely conceived, called diode zener. Which it comes constructed with an intrinsic voltage of job, that it is that typical one of stabilization.As an example: 2,7 V - 3,3 V - 4,7 V, 6v-6,1v-7,2v-9,1v-10v and therefore via in a range of values that extends from 0,78 V to 20V approximately. In figure 4 they are represents to you, on the left, the diode zener in its outer configuration, to right the symbol universal adopted electrical worker of the zener in the composition of the theoretical outlines
Fig. 4 - On the left the real configuration of a diode is brought back zener in which, in proximity of the cathode electrode, the ring is present pointer. On the right electrical worker of the zener is designed to the symbol normally adopted in the composition of the electronics project. As
it can be observed, the cathode is easy individualistic through the
ring-guide received in proximity of the electrode homonym. We resume
hour the concept, as soon as formulated to the beginning, of the
demanded inverse voltage from the operation of the diode zener. It
is to remember that one of the characteristic parameters of the
semiconductor diode is the voltage Up to now said how much, for correctly stored must find a precise application practical, with value it experiences them and didactic purpose. |
