# How do the hybrid-pi models between N-channel and P-channel JFETs differ?

This is the hybrid-pi model of an n-channel JFET.

An answer on here claimed that the only difference between p-channel and n-channel JFETs is that voltages are reversed. How would this apply to the hybrid-pi model?

I would guess that the model would be identical to the one above except for changing the sign on $v_{gs}$, so that the source is positive, gate is negative, and current flows from source to drain. But I don't have sufficient understanding to know if this is correct. Is it?

If so, what about the h-parameter model for bipolar transistors? What would differ between N-channel and P-channel?

You should note that this circuit would have been the exact equivalent to the model you provided if I swap $v_{sg}$ with $-v_{gs}$.
