Hybrid Temperature Calculations for 299 Models
The computation of Pi R depends on the fields used to specify temperature information on the hybrid form for 299 models.
• If both Hybrid junction temperature rise and Hybrid junction temperature override are blank, the system temperature plus any assembly delta temperature is used as the case temperature.
• If Hybrid junction temperature rise contains a value and Hybrid junction temperature override is blank, the value for Hybrid junction temperature rise is added to the system temperature and assembly delta temperature and then this value is used as the junction temperature.
• If Hybrid junction temperature override contains a value, this value is used as the junction temperature.
