**Part Number:**LM139A

How does one calculate the power dissipation for this part?

What is the rated power dissipation for this part?

I am looking for an electrical way to estimate the power dissipation for ex.: Pd=Vcc*ICC. Is there an electrical way to do this? I can then use the calculated power dissipation to then estimate the actual temperature rise and a junction temperature. Also what is the RATED power dissipation for this device?
