DBV package thermal resistance PCN question
The customer was listed in the Before Revision F data sheet
Designed with thermal resistance.
RΘJB = 29.6 ℃/W, ψJB = 29.1 ℃/W （ex: Revision B)
Recently, Revision F has changed the thermal resistance value of the DBV package.
Was this value a mistake from the beginning and was it fixed for the first time in Revision F?
The REF3440 data sheet (SBAS804F) page2 4 Revision History contains the following changes.
Notification Number: 20210611001
・Changed Thermal Information parameters to correctly reflect DBV package.
The thermal resistance value of the data sheet before Revision E is different.
Is the thermal resistance value written in Revision E a mistake? (Before Revision F)
RΘJB = 29.6 ℃/W, ψJB = 29.1 ℃/W
Since there is no PCN for DBV package,are the Thermal parameters of
REF3440 DBV RΘJB = 42 ℃/W, ψJB = 41.9 ℃/W from the beginning of Revision A?
I look forward to your information.
