## S29GL064S Tj_max

Hello,

Could you provide Tj(max) of S29GL064S?

MPN S29GL064S70BHI040 and S29GL064S70TFI040

## Re: S29GL064S Tj_max

Hello Naoaki-san,

The thermal resistance values in regards to the S29GL064S70BHI040 (VBK-048) and S29GL064S70TFI040 (TS-048)

are as follows:

VBK-048 (48-ball FBGA) package :

- theta j-a =  39 degrees C/W

- psi j-t =  5 degrees C/W

- typ. current =  53mA

- typ. voltage =  3.0V

- typ. Pd =  159 mW

- absolute max. junct. temp. =  125 degrees C (do not operate FLASH at 125C; operation is not guaranteed).

- max. Operating junct. temp. =  91.2 degrees Celsius  (based at max ambient of +85C).

** Please do not confuse absolute maximum junction temperature as maximum Operating junction temperature

TS-048 (48-pin TSOP) package :

- theta j-a =  45.8 degrees C/W

- psi j-t =  17 degrees C/W

- typ. current =  53mA

- typ. voltage =  3.0V

- typ. Pd =  159 mW

- absolute max. junct. temp. =  125 degrees C (do not operate FLASH at 125C; operation is not guaranteed).

- max. Operating junct. temp. =  92.28 degrees Celsius (based at max ambient of +85C).

** Please do not confuse absolute maximum junction temperature as maximum Operating junction temperature

Hope this helps...

Thank you and regards,
