Conclusions

The choice of a thyristor or a TRIAC does not depend only on the voltage, the rated current

and the sensitivity. Other parameters must be taken into account to ensure reliability.

this parameter varies with:

●

dispersion of the characteristics at manufacture

●

temperature

●

control circuit (in the case of sensitive thyristors)

●

direction of current flow.

Taking into account these elements, the designer can obtain satisfactory operation of his

circuit in industrial real-life applications.
