Hi 

I would like to request for the following information for CYUSB3014-BZXI that I am unable to locate from the datasheet:

1. Maximum Junction Temperature (Tj_max)
2. Junction-to-Board thermal resistance (Theta_JB)
3. Junction-to-Case (Top) thermal resistance (Theta_JC (Top))

Thank you!

Hello,

JC = Junction to top case.
JB = Junction To base (bottom pad which faces PCB).

Biren

Dear Biren 

 

Thank you for your very prompt reply. 

Apologies for my question, I confused it with another part. I meant to ask if the Junction-to-Case information in the datasheet refers to the case top or case bottom? 

 

Thanks
