Part Number: DP83849I

Hi team,

My customer wants to know the DP83849I Tj max.
I couldn't find it on the datasheet and E2E site.

I think DP83849I Tj max is 125℃。

Is this correct?
Please let me know.

Hi team,

I caliculated Tj_max from Ta_max, RθJA and PD_max described on the datasheet as follows.

Tj_max =Ta_max + RθJA * PD_max = 85 + 57.8 * 0.594 = 119.3℃

I believe DP83849I Tj max is 119.3℃.

Hi Fumio,

Since the Tj max temperature is not specified in the datasheet, it will not be possible to guarantee it. However, DP83849 will work in 85degC ambient temperature. Your calculation is correct and you can use that for approximation.
