Limitations of the SPICE Model
- The SPICE diode parameter, TT dominates the reverse recovery behavior.
- The diode recovers instantly after the peak reverse recovery current => hard recovery.
- The built-in SPICE model doesn't implement soft-recovery. ***
*** SIMetrix has implemented the "Lauritzen and Ma" model. Use the menu: Place > Create Model > Soft Recovery Diode on a SIMetrix schematic.
