Hi 

 

I would like to request for the junction-to-board thermal resistance (Theta_JB) information for IRFH5110PbF. 

 

Thank you!

Hello @Benedict ,

Junction to board thermal resistance is nothing but Junction to bottom case of the component, which is provided in the datasheet.

R_θja represents the thermal resistance from junction to ambient, under below conditions.
