Temperature range

Jump to solution

Hi,

For XCKU035-2SFVA784I, I want to find out both the operating and storage temperature range?

Thanks in advance for your help.

These are in the respective device family's data sheet... In this case ds892 for Kintex Ultrascale:

Are you certain that part number is correct ?

The I at the end indicates the temprature range, 

for instance ,

XCKU035-1FBVA676I which is also a I part,

has Junction temperature of -40 to 100 Deg C

but I can not find the number you specify

The part number is correct.

How does the junction temperature relate to operating and storage temperature?

the operating temprature is defined at the junction,

   if you have sufficient cooling, you an run it at any temprature ambient, if you keep the junction below the limit.

  I have a design that runs way above 100 ambient, but it uses peltie coolers to keep junction below 100.

Storage, 

 is the temperature as specified in the data sheet for the part,

but I can not find the part you refer to.

The semiconductor junctions are where most of the heat is generated so these junctions will be the hottest part of the chip.  The heat generated in the junctions must be dissipated to the surroundings.  Some heat will go into the circuit board. Some will go into the air.  Heat sinks and fans will increase the amount of heat that can be transferred into the air.  The maximum temperature of the surroundings must be calculated knowing the thermal resistance of the system, how much heat must be transferred and the difference in temperature.  It's basically an Ohm's law equation.

I understand the above explanation. Need someone to provide spec on operating and storage temperature range.

Hi @viclo3 

 

As you may know, I suggest you to make sure thermal resistance and this formula to calculate junction temperature.

Refer the following, if you want to know details.
