Question

Regarding the thermal data for the parts.

Hi team, 
Kindly assist us the below mentioned queries.

For the some ST microelectronics part data sheet, can not specify the thermal parameter such as junction to case 
thermal resistance and junction to board thermal resistance. we need those values for the thermal simulation.
so, can you please provide these data as soon as possible.
the part series number, I mentioned below: 

1) ST890DTR
2) BCP56-16
3) SMAJ5.0A-TR
4) SMAJ15A-TR
5) STL13N60DM2
6) TS924AIPT
7) STTH4R02U
8) SM6T200CA

Looking for your soonest response.

What's this, then:

Hello, 
Datasheet specify junction-ambient thermal resistance, but we need the
value of junction-case thermal resistance and junction-board thermal resistance.

Thank you. 

Looking for your soonest response.

Surely, that's the same thing?

Hi, 

No! junction-ambient thermal resistance and junction-case thermal resistance is two different things.
