C2000WARE: What is the value of Tj exactly ?

Erwin Xie

Part Number: C2000WARE

Hi TI ,

There are two description about Tj( Junction temperature ) in the datasheet of 28032 as below, one is -40C-150C, another is -40C-105C,

So could I know what is the exactly value of the Tj?

Thank you very much

The datasheet specifications are tested to the "Recommended Operating Conditions" which for your example would be 105C. So you should use that as your max Junction temperature for proper operation. Above that proper operation is not guaranteed. What the "Absolute Maximum Ratings" indicate are the conditions where the part can get permanently damaged. Please see note (1) in the table.

Thank a lot,
In the latest datasheet, the Tj in "Recommended Operating Condition" and "Absolute Maximum Rating " are both -40C-150C.

We have different temperature grade parts (S, T and Q) that are tested at different temperatures. When you order parts, that is one of the selection criteria. So you are correct that a Q grade part has the recommended and absolute max temperature the same.
