Hi,

A couple of questions, how do you know that the device is not working? Do you have the complete analysis of the circuit? Don't you have another example that indicates the malfunction of the device?

Hi...
in 3842 there SPICE model, so it does not work.
and this component has a green color - by default
indicates no SPICE model.
