Tyristor is a semiconductor device having three or more junction...
Such a device acts as a switch without any bias
and can be fabricated to hav voltage ratings of several
hundred volts to current ratings of from a few
amperes to thousands of amprees ...
The family consits of scr. .tria...diac... etc...
diode is a junction of two materials ... f
for example if its a pn junction one with excessof holes and the other with excess of electrons
