I have been looking for some tutorial or book where I can find information how to create my own LTSpice model. I would like to understand what symbol in the model mean. For example, there is below code for BAT64 diode:

* Infineon Technologies Discrete & RF Semiconductors *

* SPICE2G6 Model: Schottky Diode BAT64 series (Chip model) *

* Filename: D357_v7.txt * *

.SUBCKT D357 1 2

D1 1 2 D1

R1 1 2 440e6

.MODEL D1 D(IS=4.7n N=1.022 RS=1.6 XTI=2 EG=0.69

+ CJO=5.7p M=0.445 VJ=0.436 FC=0.5 TT=10.0p BV=42 IBV=10.0u)

.ENDS D357

I mean all symbols inside of MODEL D1 brackets: IS, N, RS, etc...

Thank you in advance for any help.

Regards,

Richard
