Default Transistor Spice Model Nodes

I got the spice model for 2n5320 on Central Semiconductor's website.
I need to use this transistor for multisim and I was just wondering how I can tell which nodes are what (1 is Emitter, 2 is Base, 3 is Collector, etc.) in the model.

Sorry I am brand new to this. Thanks in advance!

this is a native model type for spice - no further info is needed - just edit a NPN symbol's value field to the Q part number

assuming you have the library, path any .include defs under control



only subcircuit type models have to worry about pin order

What do you mean by the Q part number?

the name in the .model statement is in most cases the Q part number for convenience in reading the schematic - 2N5320 in your posted .model statement

Oh, okay. So then do I just leave it as is with "2N5320 NPN (" or am I supposed to add something further when you say edit a NPN symbol's value field.
Sorry for not understanding and thanks!
