SN65LVDS048A: Thermal Resistance

Part Number: SN65LVDS048A

Thermal Resistance, specifically the junction to cap resistance, is not given in the datasheet for SN65LVDS048A and its LVDS driver counterpart (SN65LVDS047A). Can you provide these thermal resistances for the two components?

  • The operating temperature is from -40C to +85C with Ambient Temperature (Ta) @ 25C.
  • The junction operating temperature (Tj) is 125C. 
  • Power dissipation for SN65LVDS048A is estimated at 30mW and 70mW for the 047A part.

The laminate material that we are placing this part on is FR4. This should be all the information that is needed for Junction to cap resistance. Please let me know if there are questions.
