It is in the models package [1] which is not yet in Debian. you need to build it manually. just build the one device (cf. Al's email). $ git clone https://git.savannah.gnu.org/cgit/gnucap/gnucap-models.git $ cd gnucap-models/plugins/models-ngspice17/jfet $ make gnucap on debian/x86_64 will try and find it in /usr/lib/x86_64-linux-gnu/gnucap0/, so you need to change the path in the "load" line to where it actually is. cheers felix [1] https://git.savannah.gnu.org/cgit/gnucap/gnucap-models.git/tag/?h=20171003
