Customer is considering their board design for below two parts now.
#1.S25FS512SDSBHM210
#2.S70FS01GSDSBHM210
Q1. I can see Theta JA of FAB024 package as 39degC/W in S25FS512S datasheet,but I can not see it in S70FS01GS datasheet.
Let me know the Theta JA of FAB024 for 70FS01GS.
Q2.Does AN201006 correspond above two parts?

( I would like to know refence model of the theta JA sach as JESD15 and Ta spec etc.)
Q3.Do you have specs of Theta JB (junction to board) and Theta JC(junction to case) for above two parts?
Ecpected due date : 17th.Oct.
Thank you & Regards,
Masaya

Hello Masaya San,
The values for FAB024 for 70FS01GS are theta Ja : 33.2 C/W and Psi Jt : 0.14 C/W.
Thanks,
Krishna.

Hello Masaya San,
Q1) I can see Theta JA of FAB024 package as 39degC/W in S25FS512S datasheet,but I can not see it in S70FS01GS datasheet.
Let me know the Theta JA of FAB024 for 70FS01GS.
A) Please give us some time to get back to you.
Q2.Does AN201006 correspond above two parts?
A) Yes it applies to all the products.
Q3.Do you have specs of Theta JB (junction to board) and Theta JC(junction to case) for above two parts?
A) We do not provide theta JC and theta JB thermal resistance values for our flash products. We usually give psi JT and theta JA parameters which provides a meaningful method to predict junction temperature in plastic package devices. Please find our application note "Thermal Considerations and Parameters" available at: http://www.cypress.com/file/210756/download. It explains why theta JC and theta JB values are not good approximations for plastic packages. I hope this application note is helpful for you.
Thanks,
Krishna.

Hello Krishna-san,
Thank you for your support.
Could you provide psi JT for the both parts?
