SN65MLVD048: Maximum Junction Temperature

Renan Santos Adriano

Part Number: SN65MLVD048

Hi Team,

My Customer is looking for the maximum junction temperature of SN65MLVD048RGZR. It seems that this is not available in the datasheet.

Thank you in advance for your response.

Regards,
Renan

Hi Renan,

You will need to estimate the maximum junction temperature. The equation is Tjmax= TAmax + (Pd x RθJA).

Where RθJA is the Junction-to-ambient thermal resistance, TA is the operating free-air temperature, and Pd is the power dissipation.

It looks like everything but RθJA is available in the datasheet, so I will put in a request for it. I will update this thread when I have the number for RθJA.

Regards,

I.K.

Hi Renan,

Sorry for the delay, thermal requests can take up to 2 weeks to complete. I hope to have the results by next week.

Hi Renan,

RθJA is 25.4 °C/W for this device. Using the equation in my original post, the maximum junction temperature can be estimated to be 93.6 °C.
