Again, sorry for making alot of threads, I just found this forum and I have many questions.

A while ago I built a pc board that serves as a 3 channel SS relay. The output thyristors are 25A. This circuit uses a zero cross opto coupler to fire the thyristor and turn it off (DigiKey MOC3042). I've used many of these to control aa AC wash machine motor (on/off). The first question is if I could substitute this thyristor (DigiKey Q4015L6) with a big monster one like a 520A RMS (DigiKey ST330S04P0-ND) ?

By the way, this is for my electric car, a 66 MGB.
