In a project I'm working on, I'm thinking of using some beefy SCR's as diodes by tying the anode to the gate (a practice which is usually kosher). I want to use these SCR's due to their high blocking voltage and high current ratings. But since the Gate would be shorted to the Anode, I'd eliminate one of the P-N junctions that might otherwise be there to block the reverse voltage, leaving only one P-N junction, right?
So my question is: Does shorting gate to anode on an SCR lower it's reverse blocking capability? (I guess similarly, what if my gate driver conducts between gate-anode during the reverse voltage condition? Again, would this pose a risk of reverse breakdown?)
