TS5A3159-EP: Thermal Resistance Information

Genius 13859 points
Part Number: TS5A3159-EP
Other Parts Discussed in Thread: TS5A3159-Q1

Hi Experts,

I was looking for the thermal resistance of the part TS5A3159MDBVREP and I found this link:

Bryan mentioned that we can use the approximate thermal metrics from TS5A3159DBV-Q1 (automotive equivalent) for the same package type (DBV-6P).

However, thermal impedance shown from EP's absolute rating is different to that of Q1. Refer the snapshot:

TS5A3159-EP

TS5A3159-Q1:

How is it possible? For your assistance.

Thank you.

Regards,
Archie A.

  • Hi Archie,

    Usually you can use the thermal metrics from the same package to help get an approximate calculation for some thermal information (of course, there are usually some slight differences depending on the type of device). In regards to the discrepancy here, these devices (the -EP and -Q1) were released around 8 years apart and likely have different numbers due to revisions in the way the package/thermal models are calculated since they are very similar devices.

    Thanks!

    Bryan
