  Both "thyristor" and "SCR" are
used in the U.S., but "SCR" is easier
 to spell. 
Maybe for you, but not for me ;-)

  "Thyristor" is more of a generic term that
can include
 TRIACs, DIACs, SIDACs, LASCRs, and all manner of other 4-layer
 devices. 
No! A thyristor is a semiconductor version of a thyratron. A triac is 
something different and has *never* been called a thyristor even though it 
may be seen as two anti-parallel thyristors (which is not correct).

Never say *never*; some people would disagree; e.g.:
