Part Number: UC1845A-EP Tool/software: Hi,
The datasheet for UC1845A-EP ( UC1845AMDREP) 8 pin-SOIC only lists thermal resistance, junction to ambient. Are there values for thermal resistance, Junction to Board and/or Junction to Case (bottom)?
Part Number: UC1845A-EP Hi Experts,
Our customer would like to request information on the junction-to-case thermal resistance of UC1845AMDREP. Please provide if available.
Thank you and best regards, Gerald

Hi WS,
a. Absolute Max is 150C Tj, and recomended operating temp range is (-55C to 125C Tj).
b. Will check if there is reliabilty/ qualification reports that can be shared.
c. Power dissipation will depend upon your application.
d. Theta JC will…

Hi Team,
UC2845AQ is rated for 125 Deg but here thermal resistance is higher than UC1845 CDIP and LCC package, How’s that possible?
Also UC1845A-EP is rated…

Hi Jenny,
As far as I know, TPSM846C24 module is not specifically manufactured to withstand radiation.
You may find some SEE TI products here: e2e.ti.com/.../slyt532g.pdf
Martin,
As I mentioned previously, we do not have such information. Our Modules are for commercial use therefore those tests are not performed.
I would recommend going to ti.com, click on top left corner "Applications" and select "Aerospace & defense…
