DS100BR210: Recommended Thermal Junction Temperature + Clarification on Thermal Resistances

Filipe Rubinstein

Part Number: DS100BR210

Hi all,

I am looking for some additional information regarding the DS100BR210 thermal characteristics, namely the following:

1. Recommended Operating Junction (Tj) or specifically the temperature at which full functionality is assured.

There is a spec given for recommended operating ambient temperature (85C) and Abs Max Junction (125C) for damage but does not assure full operation.

2. Do you have any data for the R_JC(bottom)Junction-to-case (bottom) thermal resistance?

3. Can you verify that the R_JC(top)Junction-to-case (top) thermal resistance is 3.2 °C/W (section 7.4 Thermal Information)?

Thank you for your consideration on this request and I hope to hear back from you soon!

Sincerely,

Filipe Rubinstein

Hi Filipe,

I'm working with a colleague to get this information and will get back to with an answer early next week. Can you share who the customer is?

Best,

Lucas

Hi Filipe,

The recommended operating junction temperature is 100C.
The junction-to-case (bottom) thermal resistance is 3.2 C/W.
The junction-to-case (top) thermal resistance is actually much larger than 3.2 C/W, it's ~35 C/W.

Best,

Lucas

Hi Lucas,

Thank you for the information!

The junction-to-case(top) thermal resistance information listed on the datasheet is incorrect and needs to be revised to the 35C/W.

Best,

Filipe Rubinstein
