| Model Description | This DIAC model was specifically
designed to provide basic performance for general usage in circuit simulation.
This model is intended to replace the common behavioral and two-transistor
macromodels found in most circuit simulators.
This is a behavioral model intended to provide basic DIAC characteristics and be sufficiently simple to provide very fast simulation times. The model is free of the simulation artifacts produced by regenerative models making it suitable for complex circuits with many switching devices. |
