TUSB8020B: Absolute Junction Temperature

May
Genius 9880 points
Part Number: TUSB8020B

Hi Team,

What is the maximum junction temperature of this IC? The only information I could find in the datasheet is the recommended junction temperature range which is -40 to 105C.

What is the reason why Maximum junction temperature is missing in the datasheet?

Thank you.

Regards,
May

    Hi May,

    We do not specify an absolute maximum junction temperature, the device should not be operated outside the recommended junction temperature range.

    Hi JMMN,

    My customer have follow questions, please see details below.

    While I understand that it is best to use the part in the recommended conditions, I have to meet a requirement to operate at an elevated temperature for a very short amount of time. Could you please ask the team if operating at 10-15°C for 30 minutes would be totally unacceptable or if it just poses the risk of a reduced part life. Is there a low power state or "standby" mode that we could put the device in for those 30 min? If 105°C is truly the max, is there another part you can recommend that we can switch to?

    Thank you.

    Regards,
    May

    Hi May,

    Operating outside the recommended range may cause reliability issues and is not recommended.  We do not have a hub with a higher junction temperature.
