Part Number: PTH12040W
My customer need the information of thermal management for the component part number PTH12040WAD.For Conduction based cooling.
PTH12040W thermal data for all airflows including thermal natural convection( Natural Conv) , no air flow, is located in the product specification pages 6 for 12Vin and page 7 for 8Vin.
The thermal (SOA derating data versus air flow at Vout .
In reply to Tom Guerin:
What will be the max allowable case temperature of each component .
How the power has been splitting for each component.
For the specified part,we have component heat sink temperature is 85°C. Will it be sufficient for cooling?
Kindly suggest us.

The thermal (SOA) safe operating area is derating data versus air flow at Vout at output current
The maximum ambient temperature is derived from the published thermal Safe operating area data on the entire PTH12040 in the product specification .The SOA data is determined by Ta ambient operating temperatures versus output current for selected output voltage
If there are any additional questions onPTH12040W, my direct contact information is firstname.lastname@example.org
Maximum Ambient temperature natural CONVECTION versus output current
Example 12Vin and 3.3Vout :absolute Maximum Ambient operating temperature at natural CONVECTION air-flow enclosed case at 0 amps to 25 AMPS IS limited to 85°°C
SOA for 12Vin and 3.3Vout
We are providing heat sink through conduction based cooling. for that case the power is fully dissipated to the heat sink and predicting the case temperature as 95°C.
