Default Re: Scr / thyristers

That particular spec means that the device has to withstand at least 200v. reverse. But there are other important specs with thyristors, especially the turn-on voltage and turn-on pulse width required. Also, you need to look at requirements for the reverse voltage width. If too narrow, the SCR won't turn off. Or, you could just slap in the replacement and look for smoke (just kidding).
