1. The customer would like to know the thermal metric(Θjc or Ψjt) and max Tj.

For TjMAX please refer to this FAQ: [FAQ] What is the maximum junction temperature (TJMAX) for a device? 

For Θjc and Ψjt please let me know what package you want this information for. You will have to give me 2 weeks to submit a request for these values.
