I have downloaded a model of a MOSFET from ON Semiconductor and have a problem with it. The "model" looks like this:

********************************************************************************
* Usage:
* This library contains 3 and 5 pin(or terminal) models. The models include 
* self heating effects and were characterized under pulse conditions from 
* 10us to 1ms conditions. 
*
* The 5p models contain 2 additional pins tj (or junction temperature) and
* tcase (or device case thermal terminal). 
* tj should always be left floating or can be connected to a very
* large resistor (>1meg). This terminal is meant to provide the user with
* output information on the junction temperature under operation. For model
* verification purposes against the data sheet and isothermal device simulations
* for example, tcase should be connected to a voltage source with value {TEMP},
* the simulator ambient temperature. For system/module level simulations that
* include thermal effects, tcase should be connected to the device-module
* thermal interface node such as the heat sink interface point.

So there is no .SUBCKT commands or something else... I haven't found any tutorials in Internet either. How can I import this model in LTSpice?

Thank you in advance!

  • \$\begingroup\$ Use it just like any other 3rd party subcircuit, except don't expect it to be shown in the flattened netlist as more than a single, cryptic line (i.e. if things go bad, you're out of luck). \$\endgroup\$ Commented Aug 19, 2020 at 15:43

  • \$\begingroup\$ @G36 Thank you, very much! That was exactly that I had looked for! \$\endgroup\$ Commented Aug 24, 2020 at 7:27

\$\begingroup\$

usually these models are made only for specific, paid-for, SPICE simulators and are not available to the wider public. It might say with which program it may be compatible, but otherwise try finding a similar model that is unencrypted that you can use with freeware.

    \$\begingroup\$ The very first line says it’s for LTSpice. \$\endgroup\$

  • \$\begingroup\$ Thank You for the answer. If you will go through the link, You will find that there are three models: for pspice, ltspice and simetrix. I have downloaded for LTSpice, so it might be right... \$\endgroup\$ Commented Aug 19, 2020 at 14:45
  • \$\begingroup\$ Well even better if it's for LtSpice. Hope it works. I know I can't use these types of encrypted models on TINA. \$\endgroup\$
