Hi Jaiganesh,

I checked internally for your request and the updates values are as follows -

  • Theta JA – 31.6 /W
  • Theta JB – 7.5 /W
  • Theta JC – 23.9 /W

Best Regards,

Hi Jaiganesh,

Thank you for contacting Cypress Semiconductor.

You can calculate maximum operating junction temperature of our devices using below formula.

Tj = Theta Ja * P + Ta

Tj: Junction temperature

Theta Ja: Junction to ambient thermal resistance

P: Power consumption of the device (VCC (max) * ICC (max)).

Ta: Ambient temperature

Please see Theta Ja values for the requested device below -

Theta Ja: 32 °C/W

Please note that we do not provide the Theta JB and Theta JC values for our devices.

You can go through the following AN for more detailed information - https://www.cypress.com/file/210756/download

Thanks for your quick response. I would like to inform you that we are planning to use your product (S25FL128LAGNFV010 of WSON 5 x 6 package) in one of our electronic equipment. To perform the thermal analysis to check the component temperature in operating conditions, we need thermal resistance value Rjc & Rjb. Please let me know if there is any way to get the information.

Thanks and Regards,
