Hi Avishek,

Thank you for this information.

We have already checked this thermal info on the datasheet. However, they are looking for the Theta JB and Theta JC, which is not provided in the datasheet.

Regards,

Cedrick

Hi Cedrick,

Extremely sorry for the delay. The product engineer who looks into the thermal modelling of this device, is out of office right now. I am actively checking with the thermal modelling team and will get back to you by tomorrow.

Hi Cedrick,

Extremely sorry for the delay in getting back to you. These results are based on simulations conducted with the device mounted on a JEDEC 4-layer PCB (2s2p and 2 oz, 1 oz, 1 oz, & 2 oz) with no thermal vias under device. Hope this helps the customer.

Parameter	Result
Theta-JB	15.6 °C/W
Theta-JC	46.2 °C/W
