This symbol represents generic TRIAC types and can be used in the following two ways:
- You can specify a subcircuit name in the MODEL parameter. In this case, make sure that the order of the nodes in the subcircuit matches the pin order of the symbol (A1, A2, Gate). If not, use the PINS parameter to specify the correct order.
- You can leave the MODEL parameter empty and specify a value for the remaining parameters. In this case the TRIAC subcircuit in the library is used.
