Hi,
I'm trying to create an SCR in Multisim using the manufacturer's Spice model. The problem is that the newly created SCR works like a diode, no matter what the gate signal is.
Here's the datasheet:

For a comparison, I designed the same circuit using a Multisim-included SCR, which works fine. At 5:31 you can see the voltage across the resistor in both cases.
So I really don't know why it doesn't work. Any thoughts?
Thank you
Michele
