SN74LVC2G07: Junction-to-Case Thermal Resistance Request

Kazuki Itoh
Genius 10065 points
Part Number: SN74LVC2G07

Tool/software:

Hi team,

Could you let me know the θJC value of devices listed below?

  • SN74LVC2G07DCKT
  • SN74LVC2G04DCKT
  • SN74LVC2G06DCKR

My customer is required to investigate θJC internally .

I asked the specific reason why they need θJC value but my customer doesn't tell me that.

Best regards,

Kazuki Itoh

    Hi Kazuki,

    Please see

    SN74LVC2G07DCKT

    Result- Theta JA-High K (standard datasheet value) 250.2
    Result-Theta JC, top (standard datasheet value) 86.8
    Result-Theta JB (standard datasheet value) 53.6
    Result- Psi JT (standard datasheet value) 1.5
    Result- Psi JB (standard datasheet value) 52.9
    Result-Theta JC, bottom (standard datasheet value) n/a

    SN74LVC2G04DCKT

    Result- Theta JA-High K (standard datasheet value) 250.2
    Result-Theta JC, top (standard datasheet value) 86.8
    Result-Theta JB (standard datasheet value) 53.6
    Result- Psi JT (standard datasheet value) 1.5
    Result- Psi JB (standard datasheet value)

    53.0

    For the SN74LVC2G06DCK We only have the datasheet values ready for the Automotive qualified device

    If this is not okay let me know and I can request for the specific OPN. This process usually takes close to 2 weeks. Possibly extended by the holiday season.

    Result- Theta JA-High K (standard datasheet value) 217.3
    Result-Theta JC, top (standard datasheet value) 152.7
    Result-Theta JB (standard datasheet value) 61.6
    Result- Psi JT (standard datasheet value) 43.7
    Result- Psi JB (standard datasheet value) 61.3
    Result-Theta JC, bottom (standard datasheet value) n/a

    Regards,

    Owen
