Part Number: TLC2543

Hi, 

Good day. I hope everything is fine. 

Our customer wants to use the TLC2543CDB and they are looking for the Theta JA for this device as well as the power dissipation for it. Can you please help us provide this to our customer? Thank you for you support. 

Looking forward to your response. 


Regards,

Cedrick

    Hi Cedrick,

    The TLC2543 has the following thermal characteristics:

    Theta JA-High K

    78.4

    Theta JC, top

    33.9

    Theta JB

    34.0

    Psi JT

    5.1

    Psi JB

    33.5

    For power dissipation - look at the operating supply current (Icc) and multiply by the applied VCC.  The typical value for 5.0V source would be 5 mW, max is 12.5 mW.
