## What is the maximum junction temperature of the device S25FL256S? The value of this parameter is not mentioned in the datasheet

Jump to solution

Hello,

For Thermal Analysis of our design we need the maximum junction temperature of the device S25FL256S. The value has not been mentioned in the datasheet also.

If anyone knows can share in this post.

Hello,

Could you please let us know the complete MPN that you use? So that, we can provide you the thermal parameters for this device and you can calculate the junction temperature based on your operating conditions. Please see our application note for more details, https://www.cypress.com/file/210756/download

Dear Sudheesh,

The complete MPN is S25FL256SAGMFIR01.I will

calculate Tj based on TA and thermal resistance of the IC.But what is

the maximum allowable TJ of the IC.

If I have derived TJ as 150 degC will the IC withstand.

Thanks & Regards
