Hello,

I can't found out the θJc Data in TRS3223EIPWR datasheet.

Could you please provide the data for me?

Best regards,

Seishin,

I will request model data. Usual turnaround time is 2 days, sometimes longer.

Seishin,

Prior to my request there was a flood of thermal request made. So I expect five more days.

Seishin,

Theta JC for TRS3223EIPWR is 24.8C/W

If you plan to measure the top of case temperature to estimate the die temperature then PSI-JT which is 1.1 C/W is the value to use.

Psi-JT is much smaller than Th-JC because very little of the device heat leaves via the top of case to air.

Theta JC is helpful when heatsinks are used on top of case.
