Part Number: TS5USBA224
Other Parts Discussed in Thread: TS3A226AE

Hi Sir

My customer wants to know the RθJC, but I didn't find it in datasheet.

Except TS5USBA224, I have two parts need to know, it's SN74LVC2G74DCTR,TS3A226AEYFFR

Can you provide TS5USBA224,SN74LVC2G74DCTR,TS3A226AEYFFR of RθJC to us? Thx.

Hi Francisco:
TS3A226AE hasn't RθJA,RθJC in datasheet
TS5USBA224 and SN74LVC2G74DCTR hasn't Tc in datasheet, I can't calculate RθJC.
Can you give a value for RθJC? or TC? Thx.

Hello Bryan

I send you the values for the TS5USBA224:
Result- Theta JA-High K (standard datasheet value)
118.0
Result-Theta JC, top (standard datasheet value)
68.3
Result-Theta JB (standard datasheet value)
24.6
Result- Psi JT (standard datasheet value)
2.0
Result- Psi JB (standard datasheet value)
24.3

In case of the TS3A226AE you have all the information necessary to get the RθJA. For more information request information on this site e2e.ti.com/.../388

For SN74LVC2G74DCTR:
Result- Theta JA-High K (standard datasheet value)
185.8
Result-Theta JC, top (standard datasheet value)
67.2
Result-Theta JB (standard datasheet value)
64.5
Result- Psi JT (standard datasheet value)
4.6
Result- Psi JB (standard datasheet value)
64.1
