I have seen a lot of posts here concerning how to fire an SCR and after reading through most of them I'm more confused now than before. I have been told that for the SCR I have the primary load goes across the large lead (anode) and body of the SCR (cathode) and the trigger signal goes across the small lead (gate) and body. To fire it I needed to add a resistor (2K or so) on the gate lead and apply a standard TTL signal (5v) to the gate which will glose the primary conenction and pass current. In my implementation (YAG laser trigger) the primary voltage is 240v so is this stating that I am to apply the 240v to the gate lead? This will burn the SCR up wouldn't it? If I were to try using a 9v battery would connecting the negative to the SCR cathode and the positive with the resistor to the SCR gate, should this cause the current to flow on the primary?
Thanks in advance....
