    Yes indeed you can, but the method depends upon the application as you can't simply connect the main terminals in antiparallel and connect the gates together.

    One way is to connect two SCRs as two branches of a bridge, with two ordinary diodes in the other two branches.

    Sorry I don't have access to drawing facilities where I am at the moment but I'm sure someone will flesh this out.
