Part Number: TMDS141

Hi Team,

Could you please provide the following thermal information since they are not shown in the datasheet?

RθJA (Junction-to-ambient thermal resistance)
Tj (Junction temperature)

Thanks!

Unfortunately, we do not have this thermal data for TMDS141.

Thanks

Hi David,

Does it have any sibling device that we can reference? These data is necessary for my customer to calculate the temperature rise of this device.

If you have any test data on this, please also share with us.

Thanks!

Max junction temperature estimation is 125C. If they want to use junction to ambient thermal resistance to calculate the junction temperature, but junction to ambient thermal resistance is not available, they can use junction to board thermal resistance to calculate the junction temperature, but instead use ambient temperature, they will use board temperature instead.

Thanks
David
