Question

Why
Semiconductor device are
preffered compared to vaccum tube devices​

Answer 1

Answer:

Being able to operate tubes at far greater temperatures than equivalent semiconductor devices allows tubes to dissipate more thermal energy for a given amount of dissipation area, which makes them smaller and lighter in continuous high power applications.

Hope this helps you
