While testing an SCR module I came across a situation I can't figure out. I have simulated the situation in Spice. Simply stated, I am connecting the gate of the SCR to the Anode, and applying DC to the anode and cathode, with a current limiting resistor in series. The thing is, when I apply negative to the Anode, and positive to the Cathode, I was not expecting current flow.
Wrong..! What am I missing? Why does this "reverse biased" SCR conduct?
