Hello team,

We have a customer that is asking for Junction-to-ambient thermal resistance value. Appreciate your help.

Regards,

    Hi Roland,

    I'm tracking down an answer and will respond with an update as soon as possible.

    Roland,

    This value is not included on the datasheet since space is a vacuum and junction-to-ambient values don't really apply without an atmosphere. If the customer desires this value for earthbound testing, I am not able to provide you with the exact value since we do not currently have access to the data taken for this part. However, I can provide you with a good approximation based on the TPS50601-SP.

    The junction-to-ambient thermal resistance for this similar part is 24.6 °C/W, which should be nearly the same as what it is for the TPS50601A-SP since both parts have the same package and dissipate similar amounts of power. 

    Hope this helps,

    Sarah
