Thermal resistances for M24128-BFMC6

[MKOTE.2]

Hi, could you provide :

• the TJmax (maximum Junction Temperature),
• RJA(Junction to Ambient Thermal Resistance),
• Rjc (Junction to Case)
• and Rjb (Junction to Board)

for the M24128-BFMC6 EEPROM.

Thanks

Hi,

See below:

• the TJmax (maximum Junction Temperature) --> 130°C
• RJA(Junction to Ambient Thermal Resistance), --> θJA=67(°C/W)
• Rjc (Junction to Case) --> θJC=38(°C/W)
• and Rjb (Junction to Board) --> θJB=27(°C/W)

Hi Pierre, 

Thanks for this answer, as Rjc is superior to Rjboard, I suppose that it is the value for Rjc top.

But as the component is a QFN with an exposed pad, is it true to take the Rjboard value for a Rjc-bottom ? 

Best Regards
