Hello Sean,

Which package will you be using: SOIC (D) or SOT-23 (DBV)?

Thank you,
Sima

Hello Sean,

Thank you. I submitted a request for the thermal values for this specific package/device. The request usually takes around 2 weeks. I will update the thread as soon as I get these values.

Best Regards,
Sima
