Version: **

 

Question: What are the θJA (Theta Ja) and θJC (Theta Jc) values of the USB-Serial devices?

 

Answer:

The thermal values for the CY7C65213 and CY7C65215 32-pin QFN packages are listed below:

  •   θJA (Theta Ja) = 20 degC/W
  •   θJC (Theta Jc) = 37 degC/W

The thermal values for the CY7C65211 24-pin QFN package are listed below:

  •   θJA (Theta Ja) = 18 degC/W
  •   θJC (Theta Jc) = 30 degC/W

The thermal values for the CY7C65213 28-pin SSOP package are listed below:

  •   θJA (Theta Ja) = 63 degC/W
  •   θJC (Theta Jc) = 27 degC/W
