How to Import Third-Party Models into LTspice (Download)
LTspice makes it easy to create and simulate schematics quickly. Sometimes the best starting point for hashing out a design is to use ideal circuit elements. However, a circuit designer will need to improve the initial simple schematic with more realistic component models.
LTspice ships with an extensive collection of third-party manufacturer models. To use one of these models, right-click the component, then click the Pick… or Select button in the properties window and select one of the models listed.
