Hello,
The package of this component is PG-TDSON-8-33. The Rthja is 50K/W with a 6 cm² cooling area on a one layer 70µm copper PCB.
Does anyone know the value of rthja for IPC90N04S5L-3R3 with MINIMAL FOOTPRINT ?

Thank you in advance for your help.

Kind Regards,

Julien Riou.

Hi Julien,

the Rthja value for a 1s0p configuration (only footprint, 70µm copper thickness, natrual convection) with footprint only for the IPC90N04S5L-3R3 will be roughly 131K/W.

The footprint only board configuration looks like this:

We are working on an application note regarding this topic which will give you the capability to get all Rthja values for all products in that package. The app. note will be available end of this year.

Best regards
