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!

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.
