    I am trying to get an SCR working in LTspice, but have had no success yet.

    I am downloading subcircuits, including them and assigning the spice model to the sub circuit file, however i either get an unknown subcircuit error or wrong number of terminals error.

    Any assistance would save my local neighbourhood from a rampage haha.
    Thanks

    Got it working!
    I was changing the spice model field, not the value field!

    Now if anyone wishes to aid me in finding a scematic or simulation for a half-controlled rectifier, i wouldnt argue.

    Here is one:
    I didn't check it to see if it is in spec. For demo only.
