Hi.
How can I get information about any diode, such as these for the NSPW500BS (or hcpl0701_led) diode example (and which are needed to create a new model for an LED in LTSpice):
.model NSPW500BS D(Is=.27n Rs=5.65 N=6.79 Cjo=42p Xti=200 Iave=30m Vpk=5 mfg=Nichia type=LED)
and
.model hcpl0701_led D(IS=1E-14 N=1.14 CJO=40p M=0.333 VJ=0.75 ISR=1E-10 BV=100 TT=5E-9 TYPE=LED)
I need such the data for the diodes LED5C F5V-IT-RE-RE LED 5mm, red, 625nm B123 and for this LED.
Sellers' do not say that information.
Mostly they only list the ones mentioned above, for my diode.
For example, resistors are easy to enter, we get all the data for them in the specifications from the resistor seller and just enter them, but this is not the case with diodes.
Thanks.

If you can't get model parameters from the diode manufacturer, you have to buy the diode, make measurements and estimate the parameters yourself.
Has anyone worked in LTSpice? And that he has experience with inputting new libraries, symbols, models, ...
Lots of Arduino forum members use LTSpice. I put new models in rather frequently, but usually get them from the web. There is an LTSpice forum where you can sometimes find such things.
But I think they don't mention it probably because it is possible to somehow calculate it based on the standard data from the product specification??
Or is it somehow standardized based on the name of the diode, maybe there is an online service somewhere to identify the diode by name.
Not everyone has such instruments for such measurements.
