## Tjmax for S25FL256LAGNFB010

Hi Team,

Please let me know Tjmax for S25FL256LAGNFB010.

I understand that Tj@Pdmax​ is 108.888℃ for S25FL256LAGNFB010.

Tj@Pdmax = ( 18 x 0.216 ) + 105 = 108.888 ().

At this time, I am required Tjmax for S25FL256LAGNFB010, so please advise this.

Or, please provide Flash Memory version of AN4017.

Thanks and regards,

Hello,

･Absolute Maximum Junction temperature with the Power Applied = 125℃.(do not operate FLASH at 125C; operation is not guaranteed).

･Maximum Operating junction temperature =  108.9℃  (based at max ambient of +105C).

Answer: Based on my calculation, max operating junction temperature at Pd max should be as follow.

- theta ja =  18 degrees C/W

- max current =  50 mA

- max voltage =  3.6 V

- Pd max =  180 mW

- max. Operating junct. temp. =  (106.8 C  (based at max ambient of +105C)

Thanks,

Hello,

I guess you are asking for the Absolute Maximum Junction Temperature for this device. Please correct me if my understanding regarding your query is not correct. The Absolute Maximum Junction temperature is +150C without Power Applied, +125C Max with the Power Applied.

Let me know if you need any clarification.

Thanks,

I understand that there is no Tjmax spec in the datasheet because Flash memory almost does not need to consider self-heating.

So, I asked "Absolute Maximum Junction Temperature".

Is my below understanding correct?

･Absolute Maximum Junction temperature with the Power Applied = 125℃.(do not operate FLASH at 125C; operation is not guaranteed).

･Maximum Operating junction temperature =  108.9℃  (based at max ambient of +105C).

Thanks and regards,
