Hi Junsong,

Thanks for reaching out

The device temperature protection is characterized for MMBT3904. We suggest to use the same part.

Best regards

Hi Junsong,

Based on the ideality factor of the BJT, the TSD threshold will change slightly. What is the ideality factor of PMBT3904-QR Nexperia ? so that i can check.

Best regards

Rakesh
