DS34C87T: Request for Thermal Resistance information

Jonathan Geronga

Part Number: DS34C87T

Hi Team,

Can you tell me the complete thermal resistance information (ThetaJB, ThetaJC, and also ThetaJA) for DS34C87TMX?

Thanks,

Jonathan

Jonathan,

This is an older device so we are looking into it. This may require us to submit a request to our thermal modeling team, so please be patient as we try to find this data.

Thank you very much for your patience.

Jonathan,

Thanks for reaching out. Thermal model model requests typically take about 2-3 weeks to fill. I will follow up here when the information for the DS34C87TMX is obtained.

Best,

Danny

Hi Danny and Eric,

Thank you for supporting this thread.

I will inform the customer of the possible lead time on getting the thermal information.

Regards,

Jonathan

Jonathan,

Thanks to the great work of our thermal/packaging team, this request was filled much more quickly than expected. Here is the data for your request:

Thermal Analysis for DS34C87TMX

Parameter		Value	Unit
R_θJA - High K	Junction-to-ambient thermal resistance	81.1	°C/W
R_θJC(top)	Junction-to-case (top) thermal resistance	38.3	°C/W
R_θJB	Junction-to-board thermal resistance	39.6	°C/W
Ψ_JT	Junction-to-top characterization parameter	5.3	°C/W
Ψ_JB	Junction-to-board characterization parameter	39.3	°C/W
R_θJC(bot)	Junction-to-case (bottom) thermal resistance	N/A	°C/W

Best,

Danny
