The initial install of LTSpice comes with a limited set of JFET models stored in a filed called Standard. The method of data entry varies between characteristics. Starting with LTspice XVII, control panel settings were added to allow the user to. Remember however that we are not using a regular diode model for our diode; we are using a. diodes disclaimer. The circuit was built from the digital gates in the component library supplied with the original Linear Technology's free LTspice tool. There is a generic Zener Diode in the library but this does not allow for editing. You may try to import additional diode model besides sticking to the default diode library. A couple of people have sent models (Thanks, guys), but there is one There's something weird about the diode model in LTSPice--it really really doesn't like zero impedance loads. However, when it comes to model opto electronics components, the SPICE program does not possess the capability to evaluate or simulate opto electronics components with outputs measured in radio-.
