DS64BR111: Storage temperature

Mikael Carlsen

Part Number: DS64BR111

Hello,

I was considering to use DS64BR111 until I saw that the storage temperature was -40 deg C, I need to find an alternative.

I need -55 deg C for storage.

Are there any alternative to use?

Hi Mikael.

I don't see any direct replacements. I'll find out more about the -40 storage limit.

Will the device be power up during this time?

Thanks and Regards,

Lee

Hi Lee,

Thanks for the replay.

Yes, the device will be powered up at -55.

Hi again,

Wrong answer from me. During test, our DUT will be stored in -55 degrees (min 3 hours). After that, the temperature is increased. When it reach -40 (plus 2 hours for temperature stability) the power will be turned on.

Hi Mikael,

I don't think 3 hours will be any issue at -55C. When testing to failure we focus on high temperature limits. This package and process has passed testing after 1000 temperature cycles from -65C to 150C

Lee
