What are the thermal resistances for the MAX6138 parts? In particular, I am looking for MAX6138AEXR21+T & MAX6138AEXR30+T. If the junction temperature is listed in the datasheet, the rise to that junction temperature in theory should also be available. 

The legacy maxim datasheet provided the following in the absolute max ratings... https://www.analog.com/media/en/technical-documentation/data-sheets/MAX6138.pdf 

Continuous Power Dissipation (TA = +70°C)

3-Pin SC70 (derate 2.17mW/°C above +70°C)...........174mW

Operating Temperature Range........................... -40°C to +85°C

Storage Temperature Range............................ -65°C to +150°C

Junction Temperature......................................................+150°C
