Original question:

TPD2E001-Q1 Temperature range

TPD2E001-Q1: TPD2E001-Q1 vs TPD2E001

Part Number: TPD2E001-Q1
Other Parts Discussed in Thread: TPD2E2U06, TPD2E2U06-Q1, TPD2E001

Hi Team,

My customer is trying to find an alternative with the Nexperia crisis for an automotive program and they had two questions. 

Is the TPD2E001-Q1 vs industrial version the same IC die, one is just auto qual'd even though it's only up to 85C? 

They are also considering TPD2E2U06-Q1 for this program, but the pin to pin package drop in is only industrial grade. They are trying to convince the OEM to use the industrial grade part, so they were wondering if the TPD2E2U06-Q1 vs TPD2E2U06 is the same IC die and the only difference is the A/T qualification across temp and we don't gurantee performance up to 125C for the indsutrial grade?

Regards,

    Hi Cameron,

    I will talk to our product engineering team to confirm this information. 

    Best,

    Hi Cameron,

    TPD2E001-Q1 and TPD2E001 both have the same die. These are old parts so we are not sure why it's auto qual'd even though it's only up to 85C.

    TPD2E2U06-Q1 and TPD2E2U06 have the same die and yes, we should meet up to 125C (operating free air temperature) for the industrial grade as it is stated in our industrial datasheet. The only difference I see is that the peak pulse power for the TPD2E2U06 DRL package is higher which is good for the customer. Please make sure to emphasize that although it works the same, it is still not automotive qualified.

    Let me know if you need anything else.

    Best,

    Bryan

    Thanks Bryan, this is helpful. Does TPD2E001 and TPD2E2U06 use a similar silicon deisgn then as well? Or since they are different process technologies are they extremely different? If the TPD2E001-Q1 or TPD2E001 are used in an application where the ambient temp can reach 110C, we would still expect the part to perform since the abs max is 150C? I.e. Reverse leakage current increases at higher temp, but not dramatically different from typical diode (Leakage roughly doubles for 10 C increase). The capacitance variation increase would be limited. The performance parameters just aren't spec'd and it would be up to the customer to analyze the performance parameters?

    For TPD2E001 the max operating temperature is 85C. The 150C you see in the datasheet for this device is only storage temperature. I would not recommend customer to use this device over the max 85C. If they really need to use it, they would need to do some testing to make sure there aren't any problems with it's functionality. I would still recommend TPD2E2U06 since it has better specs all around, it's a newer device and its operating temperature is from -40 to 125C. Also for TPD2E001, the leakage current increases at higher temp as you can see in the datasheet but it is only spec'd at 85 degrees. If the temperature is higher than this, this could cause leakage current to spike exponentially more compared to what we see in the graph specially if part fails short.

    The die process is different on TPD2E001 compared to TPD2E2U06 since TPD2E001 is a very old part.

    It is up to customer to test our device out of recommended operating conditions but it would most likely cause permanent damage to it.

    Best,
